I have a chicken-or-egg deadlock: I am trying to get onto irc.debian.org, but it's /actually/ irc.oftc.net. Biboumi by default tries to use SSL (which is good!) but fails because their SSL is haphazardly configured. They are returning a name that doesn't exist in the DNS right now (I don't know how they got a cert like that issued; maybe their phasing out the name?), without the alt names for irc.oftc.net and irc.debian.org like it should have.

$ openssl s_client -connect irc.debian.org:6697
CONNECTED(00000003)
depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3
verify return:1
depth=0 CN = larich.oftc.net
verify return:1

Since it doesn't exist, I can't work around by connecting to that name either.

I could work around any of these if I could get to the Biboumi Ad-Hoc command to configure a server (a la https://lab.louiz.org/louiz/biboumi/blob/8.3/doc/biboumi.1.rst#id43 -> On a server JID -> Configure -> Verify Certificate), but because I'm not connected yet, I can't, Gajim won't let me send Ad-Hoc commands to offline JIDs:

I don't know what to do about this. Do you have any suggestions? If adding a transport JID made it appear online I could deal with this.

Thanks for biboumi, I use it daily :)
