Yes, I did generate the certificates and place them in

/etc/ssl/certs/
/etc/ssl/private/

I'll try to regenerate them again, just in case something went wrong.

I connected from the same subnet my server is located. I'll try to
connect from somewhere else outside of my LAN and report back if
successful. Thanks.
