+===== Cause =====
+The SSL_ERROR_RX_RECORD_TOO_LONG message from Firefox typically comes as a result of a mis-configuration on the server side.
+The two most predominant causes of the SSL_ERROR_RX_RECORD_TOO_LONG message from the server side:
+  * The listening port mis-configured – If you want your website to establish secure connections you must configure it to use Port 443.
+  * The system does not support an adequate TLS version – This problem arose ten years ago with the advent of TLS 1.2 and is appearing again with TLS 1.3.
