If you are getting the ssl_error_rx_record_too_long nginx error message on a regular basis and it prevents you from visiting different sites, we advise you to take a look at the solutions that we’ve listed down below. Hopefully, one of them would be the solution that fixes the issue for you and makes the ssl_error_rx_record_too_long nginx error go away.

Ssl_error_rx_record_too_long Firefox Fix

Fix 1: Change the site URL from HTTPS to HTTP

As simple as this might sound, it could indeed do the job in some cases. Since it’s the easiest fix from this article, we offer it to you first. Simply replace the https:// in front of the URL of the site you’re trying to visit with http:// and try to go to the site. Even if the https:// is not visible in your URL bar, put a http:// in front of the site URL so that now this is the protocol that would be used.

Fix 2: Change Firefox Proxy Settings

  1. Open the Firefox main menu and go to Settings.
  2. In the settings search bar, type proxy settings and then click on the settings button from the result that gets shown.

  3. Now, click on Restart – the browser should now get restarted with no add-ons enabled.

If the error goes away, then it was most likely getting caused by one of your add-ons. In such a case, you can start Firefox normally, manually disable all add-ons and then start re-enabling them one by one with a restart after each consecutive add-on gets enabled in order to test which one(s) is problematic. To disable/enable Firefox add-ons, go to Add-ons from the main menu and simply switch on/off the toggle buttons next to each add-on.

Fix 4: Refresh Firefox

  1. In the URL bar, type about:support and hit Enter.
  2. In the page that opens, click on the Refresh Firefox button.

  2. Click on I accept the risk in order to get allowed to visit the next page.
  3. In the search box at the top, type security.tls.version.max and double-click on the first result.
  4. Set the integer value to 0 and click on OK.
