I'm getting the same error and haven't been able to find any documentation on it. Anyone else?
thanks.
Until this issue is cleared up I started pinging manually from Ping-O-Matic.
http://pingomatic.com./No error messages so far.
I unchecked MT's automatic ping in settings first.
You might want to give it a try.
