How to Fix “Your Connection is Not Private” Error

There are a few different ways to fix or bypass this error message for each browser.

1. Reload the Page

Of course, this seems like the most obvious thing to try, but something simple can do the trick. Sometimes, fixing common glitches like your browser timeouts, internet connections, and typos can solve the problem.

2. Try Incognito Mode

The next thing that you can try is to enter incognito mode and attempt to access the same website. If the website is truly having security issues, then it should not work once you switch to incognito because this mode lets you browse without saving your history or cache. If the site still says “your connection is not private,” then you should try clearing your cache.

To open your Chrome browser in an incognito tab, go to the three vertical dots on the top right of your screen. Open the drop-down menu and select “New incognito window” or hit the keys ctrl+shift+N.

3. Check the Date and Time

Double-check that the date and time on your computer are correct. When they don’t match the browser, an SSL connection error may occur.

How to Check Date and Time on a Mac

  1. Go to the Apple menu in the upper left corner of your screen.
  2. Click on System Preferences.
  3. From there, choose Date & Time.
  4. Ensure the date and time are accurate.

How to Check Date and Time on Windows

  1. Right-click the date and time on the taskbar.
  2. Click on Adjust date/time.
  3. Verify the date and time are correct.

4. Clear Your Browser Cache and Cookies

While browsing online, your computer stores cookies that gather data and take up tons of space on your hard disk. When your computer is trying to process all of that information, it can really slow down

Try going to your settings and clearing your browser cache and cookies . Clearing all that information will speed up your connections .

5. Consider What Wifi is in Use

Using public wifi might give you a warning because it’s not secure. Some public wifi has poor configuration and does not run HTTPS. If you are uncertain about the security of your connection, look for a different wifi network or wait until you can browse safely at home.

The best way to protect your data while on public wifi is to use a Virtual Private Network (VPN) . A VPN helps to hide your traffic and protect your identity while it exchanges encrypted data to and from a distant server.

6. Check Your Antivirus or Firewall

If you have an antivirus on your Mac or Windows device , you may still be receiving the error message because the antivirus or firewall is overriding your network. Test this issue by temporarily disabling the SSL scan feature.

7. Manually Proceed With Caution

If you are still seeing a “Your connection is not private” message and you are in a situation where you must reach your desired website, do so with caution. Your browser shows you this message and advises against continuing for good reason.

Choosing to proceed you may be putting your personal information and payment information at risk of being compromised. The time and money involved with this risk are not worth it.

If you follow these steps, you should be able to fix or bypass the “Your connection is not private” error message. Remember that you are receiving this message because the website you are trying to access is not deemed secure. If you fail to fix the issue, bypassing may help you find what you are looking for, but also risk your private information. There is software like Panda Security Dome that you can use to protect your digital life. Your online information holds great value, be smart with your searches so that your information doesn’t end up in the wrong hands.

Panda Security

Panda Security specializes in the development of endpoint security products and is part of the WatchGuard portfolio of IT security solutions. Initially focused on the development of antivirus software, the company has since expanded its line of business to advanced cyber-security services with technology for preventing cyber-crime.

Form Submission Redirects

When you submit a regular HTML form, the browser will follow the HTTP(s) request.

If your back end server handling the /submit route does a 30x redirect to a different superdomain, you will get a cross-origin error.

A common use case for this is Single sign-on (SSO). In that situation you may POST to a different server and are redirected elsewhere (typically with the session token in the URL).

If that’s the case, you can still test this behavior with cy.request() . cy.request() is NOT bound to CORS or same-origin policy.

In fact we can likely bypass the initial visit altogether and POST directly to your SSO server.

If you still want to be able to be redirected to your SSO server, you can read about disabling web security.

Fix ERR_SSL_PROTOCOL_ERROR by checking your Antivirus Settings

Warning: This step isn’t entirely safe as it allows the older, insecure SSL/TLS protocols that some of the websites still use.

You might not know this, but your Antivirus software keeps an eye on the web pages you visit and protects you against any threats they may pose or contain. It does this by checking the SSL/TLS protocol a website uses. Upon finding the protocol to be unsafe and outdated, it prevents you from visiting the site.

There isn’t any one particular way to change the settings for all Antivirus software as the UI and settings differ from one software to another. You’d have to find and see if it’s scanning the SSL protocols. If it does, disable it and see what happens. If the problem persists, revert to the original settings.

Editor’s Note: Generally, the reason you will see an antivirus program cause alarm about an SSL/TLS connection is because the server is attempting to negotiate a connection using a deprecated or vulnerable SSL or TLS version such a SSL 3.0 or TLS 1.0. As we’ve written in similar advice articles, don’t tamper with your antivirus or reduce your TLS version settings to accommodate a website’s bad SSL/TLS configuration. The risks far outweigh the rewards.

If you attempt to connect to a site that has a missing, invalid, or self-signed SSL certificate using an HTTPS URL, your browser shows a security warning such as ‘Your connection is not private’ in Chrome or ‘Potential Security Risk Ahead’ in Firefox. For example:

Checking the JavaScript console

You could also check the JavaScript console in your browser. This may also display a warning as to why the site is not loading.

In FireFox and Chrome, you can open the console by pressing the following keys:

  • Windows — Ctrl + Shift + i
  • Mac — Option + Cmd + i

Click the console tab.

You may see the following warning in the console.

Handle mixed content at scale #

The manual steps above work well for smaller websites; but for large websites or sites with many separate development teams, it can be tough to keep track of all the content being loaded. To help with this task, you can use content security policy to instruct the browser to notify you about mixed content and ensure that your pages never unexpectedly load insecure resources.

Content security policy #

Content security policy (CSP) is a multi-purpose browser feature that you can use to manage mixed content at scale. The CSP reporting mechanism can be used to track mixed content on your site, and provide enforcement policies to protect users by upgrading or blocking mixed content.

You can enable these features for a page by including the Content-Security-Policy or Content-Security-Policy-Report-Only header in the response sent from your server. Additionally you can set Content-Security-Policy (though not Content-Security-Policy-Report-Only ) using a tag in the section of your page.

Modern browsers enforce all content security policies that they receive. Multiple CSP header values received by the browser in the response header or elements are combined and enforced as a single policy; reporting policies are likewise combined. Policies are combined by taking the intersection of the policies; that is to say, each policy after the first can only further restrict the allowed content, not broaden it.

Finding mixed content with content security policy #

You can use content security policy to collect reports of mixed content on your site. To enable this feature, set the Content-Security-Policy-Report-Only directive by adding it as a response header for your site.

Content-Security-Policy-Report-Only: default-src https: ‘unsafe-inline’ ‘unsafe-eval’; report-uri https://example.com/reportingEndpoint

The report-uri response header is being deprecated in favor of report-to. Browser support for report-to is currently limited to Chrome and Edge. You can provide both headers, in which case report-uri will be ignored if the browser supports report-to .

Whenever a user visits a page on your site, their browser sends JSON-formatted reports regarding anything that violates the content security policy to https://example.com/reportingEndpoint . In this case, anytime a subresource is loaded over HTTP, a report is sent. These reports include the page URL where the policy violation occurred and the subresource URL that violated the policy. If you configure your reporting endpoint to log these reports, you can track the mixed content on your site without visiting each page yourself.

The two caveats to this are:

  • Users have to visit your page in a browser that understands the CSP header. This is true for most modern browsers.
  • You only get reports for pages visited by your users. So if you have pages that don’t get much traffic, it might be some time before you get reports for your entire site.

The Content security policy guide has more information and an example endpoint.

Alternatives to reporting with CSP #

If your site is hosted for you by a platform such as Blogger, you may not have access to modify headers and add a CSP. Instead, a viable alternative could be to use a website crawler to find issues across your site for you, such as HTTPSChecker or Mixed Content Scan.

Upgrading insecure requests #

Browsers are beginning to upgrade and block insecure requests. You can use CSP directives to force automatic upgrading or blocking of these assets.

The upgrade-insecure-requests CSP directive instructs the browser to upgrade insecure URLs before making network requests.

As an example, if a page contains an image tag with an HTTP URL such as

The browser instead makes a secure request for https://example.com/image.jpg , thus saving the user from mixed content.

You can enable this behavior either by sending a Content-Security-Policy header with this directive:

Or by embedding that same directive inline in the document’s section using a element:

As with browser automatic upgrading, if the resource is not available over HTTPS, the upgraded request fails and the resource is not loaded. This maintains the security of your page. The upgrade-insecure-requests directive will go further than automatic browser upgrading, attempting to upgrade requests that the browser currently does not.

The upgrade-insecure-requests directive cascades into documents, ensuring the entire page is protected.

Blocking all mixed content #

An alternative option for protecting users is the block-all-mixed-content CSP directive. This directive instructs the browser to never load mixed content; all mixed content resource requests are blocked, including both active and passive mixed content. This option also cascades into documents, ensuring the entire page is mixed content free.

A page can opt itself into this behavior either by sending a Content-Security-Policy header with this directive:

Or by embedding that same directive inline in the document’s section using a element:

If you set both upgrade-insecure-requests and block-all-mixed-content upgrade-insecure-requests will be evaluated and used first. The browser will not go on to block requests. Therefore you should use one or the other.
