How to Fix the SSL_ERROR_RX_RECORD_TOO_LONG Error Message?
What Is the Mozilla Firefox Error Message SSL_ERROR_RX_RECORD_TOO_LONG?
Most of the time, due to the following two reasons, the SSL_ER ROR_RX_RECORD_TOO_LONG error message is displayed from the server-side:
- The listening port is misconfigured. For example, the website you want to establish a secure connection with is not configured to use Port 443.
- Adequate TLS version is not supported by your system.
Upgrade Your Support for TLS Version
Also, upgrading Open SSL differs from one server to another, but many documentations are available.
