If you enable "Display invalid certificates for approval" in Options/Connect/Options/SSL, what does it show as the error in the SSL Warning dialog when you try to connect?
A window like this opens:
I click on the "OK" button and a new attempt to connect to the server starts:
* [10101] Host disconnected
* Disconnected
* Connect retry #2 irc.epicnet.ru (+6668)
*** Connecting to IRC chat ...
After that, all subsequent connections to the server occur without failures and errors
:-]The test was done on
mIRC v7.66 (
not beta).
