s2s problem

I've installed a jabberd server (0.7.5) and played with configuration for some time. Everything worked ok, to the moment, when i created a file "pl.msg" with my translation. By accident i saved it as iso, not utf encoding, and after restarting discovery didn't work. I saw the mistake and converted pl.msg to utf. Discovery for my host worked and i had text translated, but suddenly i couldn't connect to any server. I deleted the pl.msg file and changed back to "en" lang, but i still can't connect to other servers (except for my other jabberd2.0 server - that conn. works fine, which is strange).
When trying to disco/browse s2s connection hangs (it is listed on outgoing s2s connections) and netstat says:
tcp 0 1 62.93.33.52:41427 XXX.YYY.ZZZ.AAA:5269 SYN_SENT
Nothing else happens.
I tried connecting to servers, that haven't ever communicated with mine, but they also don't respond. It's hard to belive that translation broke this, but it was the only change that i made, before it stopped working. I stopped the server, and killed all erlang processes many times - it always happens.
Any suggestions?
