SSL Error With Certificate From ZeroSSL

Post by sadan »

I have obtained an ssl certificate from zerossl.com and installed it on my server, however upon connecting I get this error:

Code: Select all

Using the self signed certificate from the install process only results in the self signed certificate warning.

A certificate can't be verified when the hostname that should be in the CN is set to an IP.

I assume that you're giving a hostname like irc.domain.tld when UnrealIRCd generates the it?

Also, why don't you use Let's Encrypt, instead?
