Works for me. Your ip may be throttled (because of trying too frequently) or Z:lined.

I cannot make SSL connection in any way.

unreal version?
have you checked the ssl settings?
https://www.unrealircd.org/docs/SSL_Cip ... _protocols

listen {
ip 185.126.176.53;
port 6697;
options { tls; };
};

set {
ssl {
protocols "All,-TLSv1,-TLSv1.1";
ciphers "EECDH+CHACHA20 EECDH+AESGCM EECDH+AES+SHA384 EECDH+AES+SHA256";
};
};

Right, so you are using modern settings (you have disabled TLSv1.0 and TLSv1.1).

What client are you using? Possibly your client is too old? Like an mIRC version from several years ago?

Another way to trace this is to look on the IRCd side. If an IRCOp on the IRC server sets the eyes and junk snomask they will see more information when you try to connect (MODE yournick +s +ej). They may see some more details such as "unsupport SSL version".

mIRC Client ? Unrealircd 4 no problem 5 problem.. mIRC 6,35

so the problem is that your client is way outdated.
unreal4 didnt care soo much about tls/ssl you can read about this in the release news / highlights.
please upgrade your mirc or try to use something else.

(or, just change things in your conf, like ssl protocol and ciphers; but i wouldnt recommend that one)

This version has almost 12 years. It's outdated, deprecated, full of bugs and it's a security risk!

Most people use such old versions because they can crack it so they don't need to pay a license.

If you don't want to use a newer version of mIRC because of that, you can try AdiIRC or even HexChat (both for Windows and free software), but don't use such old mIRC versions.

As stated above by someone, don't change the IRCd TLS protocols/ciphers. You would endanger your IRC server.

Again, you should really consider updating your mIRC client or to use one of the alternatives I've suggested.

Cheers

You can use these files to prevent the mirc problem.

Actually. mIRC v6 didn't include ssl libraries and one would need to install them separately for mIRC to use. I suggest trying to get the official ssl package from the official website.

Update for clarity: mIRC v6 supports ssl server connections, but doesn't include the ssl libraries as new versions do. While using v6, you'll need to install the libraries separately and mIRC will see and use them accordingly.
