Hi, all.
Didn't know where to write on this site.
I've got a problem with Prosody.

Everythign is set up. Got Prosody, got candy chat plugin on my website, got bosh but I'm not the one who set it all up.

Everythign was working fine, people were login to chat room and could talk there, but after a week or so, today the chat stoped working, when you try to login on the website it just stays on "connecting"
you can check the site on http://bociany.tv

Does anyone now hat the issue may be? There were no file changing in the server or in the website files.
