What is the SSL_Error_rx_record_too_long Error?
SSL_Error_rx_record_too_long is an error that occurs exclusively on Mozilla Firefox. It’s quite a common error and it happens due to issues with the SSL certificate. This error occurs when the port a client is connecting to is opened on the server but the SSL certificate is not properly configured.
