How to resolve Mozilla Firefox error code: SSL_ERROR_RX_RECORD_TOO_LONG

The SSL_ERROR_RX_RECORD_TOO_LONG error pops up when a configuration error occurs on the server. According to our Support Techs, we can resolve the error by trying out these troubleshooting tips:

• Upgrade support for TLS version
• Configure correct listening port

How to upgrade support for TLS version

TLS 1.3, also known as RFC 8446 is one of the latest versions. We have to check whether the SSL/TLS library is up-to-date. In case the server does not support TLS 1.3, our Support Techs recommend ensuring support for TLS1.2 if available.

Our Support Team also suggests disabling TLS 1.1 to avoid the SSL_ERROR_RX_RECORD_TOO_LONG error.

How to configure the correct listening port

The correct listening port for HTTPS traffic is 443. If the port does not match or in case the trusted SSL/TLS certificate is not on this port, you will face the SSL_ERROR_RX_RECORD_TOO_LONG error.

Our Support Techs recommend configuring the correct listening port to avoid the error.

How to fix the error as a user

If you have been coming across the SSL_ERROR_RX_RECORD_TOO_LONG as a user, try one of the following methods:

1. Clear the cache
   Although clearing the cache may not always resolve the error, it has been successful in many cases. We can verify this by opening the website in a Private or Incognito window. We can also try Ctrl+Shift+ R to get the job done.
2. Editing security.tls.version.max
   This method involves opening a new tab in Mozilla Firefox and entering “about:congif” in the address bar. Then, we have to click the “I accept the risk” button and search for type: security.tls.version.max in the search field.

   After that, we have to change the value from 4 to 3 in the pop-up. This workaround solution will help resolve the error till you upgrade the TLS version.
