Mailkey, Chatkey does not match
 

Its strange, from my laptop I dont get a connection to my servers chatserver anymore, showing the error "Chat key for .... does not match, closing connection".

Logging in from my main PC, it works flawlessly. Restarted server machine, EQ server, chatserver, but to no avail.

Any idea how to fix that issue without disabling chatkey verification in the rules?

Thanks in advance.
