Firefox Error Fix

Your connection is not secure
An error occurred during a connection to server1:8146.
server1 uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.
Error code: NS_ERROR_NET_INADEQUATE_SECURITY

open Firefox new tab then type about:config

network.http.spdy.enabled.http2

Change above value to false then try again accessing.

That’s it.
