"ERR_SSL_VERSION_OR_CIPHER_MISMATCH" error in a web browser when trying to open Gaia Portal Technical Level
Symptoms
  • "ERR_SSL_VERSION_OR_CIPHER_MISMATCH" error in a web browser when trying to open Gaia Portal.

  • Traffic capture on Gaia OS on the applicable interface (tcpdump with '-s0 -w' flags ) shows that Gaia OS responds with "Fatal, Description: Protocol version (70)" to "Hello" packet from the web browser client.

Cause

When you configure Gaia Portal to listen on the TCP port 4434, Gaia OS uses the httpd2 demon.

The corresponding configuration file /web/templates/httpd-ssl.conf.templ does not have TLSv1.2 listed in the SSLProtocol directive.
