Getting kicked from server

[Slartybartfast 76]

I have a strange problem. Been playing dayz mod for over 4 years and never had any issues. Until a few days ago. 

Whenever I join a (vanilla) server I get kicked after 1 or 2 minutes without any warnings. At first I thought it was the specific server but it's happening on every server now. I asked the host to look at the log files and this is what is saying:

 

Line 5800: 13:20:36 "INFO - Player: Slartybartfast(UID:76561198032273427/CID:44174) Status: CLIENT LOADED & PLAYING"

Line 6857: 13:23:30 Message not sent - error 0, message ID = ffffffff, to 1826973740 (Slartybartfast)

Line 6860: 13:23:30 Message not sent - error 0, message ID = ffffffff, to 1826973740 (Slartybartfast)

Line 16651: 8:36:23 Message not sent - error 0, message ID = ffffffff, to 1118040321 (Slartybartfast)

 

I tried reinstalling Arma 2, Arma 2 OA and Dayz mod but still get the same issues.

 

Any ideas?

 

Thanks in advance
