Tigase seems to have generated a self-signed certificate for the pubsub domain by itself I didnāt notice it. I replaced it with a newly emitted single certificate for both main and pubsub domains. Letās hope it works now.
Yes! It works now

I triggered this connection manually via Gajim, I will wait until a new connection not initiated manually by me occurs and take a look at what gets exchanged.
