Getting 503 service unavailable response when trying to add buddy

Submitted by vsydorov on Thu, 2015-09-17 09:47

I am trying to set up the ejabberd XMPP server on the VPS server (Digital Ocean, FreeBSD droplet). I had started the ejabberd service and was able to log into the developer console, register a user and log in. The problem that I right now have is that I cannot "add buddy" or start any s2s connections whatsoever as I get a 503-service unavailable error.

This is the debug output of me trying to send a Buddy request to my friends account (I replaced his real handle with "HANDLE"):

At first I though my DNS table was wrong, but I check and rechecked it again and againt - it's correct.

_xmpp-client._tcp.vsydorov.me. 1800 IN SRV 5 0 5222 vsydorov.me.
_xmpp-server._tcp.vsydorov.me. 1800 IN SRV 5 0 5269 vsydorov.me.
