I'm unable to conversate with people from other servers

Hello,

I’m not sure whether this is the right place to ask, but I’m a bit stuck ; I recently upgraded Openfire on my server and am now using the version 3.7.0

Even though I had no problem before and had not had to change any option, I’m now unable, when connected on this server, to conversate with people from other servers, whatever the other server is. I can, though, talk with the only friend I have on MY server.

I guess it has to do with the Server Settings, but I have no clue which one I should touch and I don’t want to break anything.

The daemon is running on Debian 6.0.1, on which I’m not using a firewall.

What should I try ? Could it have something to do with SSL certificates ? (I’m asking this last question because everytime I connect I get :

[12:18:02] SSL status:1

[12:18:02] Certificate is not trusted!)

Here is the complete error log : http://paste2.org/p/1473121

… and the warn log : http://paste2.org/p/1473123

Thank you in advance !

No idea ?
