When I send an instant message to a contact shortly after I receive the error as in the title
WLM 8.5 (patched)
Windows XP SP3, I use ProxHTTPSProxyMII v1.5 as suggested
What error are you receiving? Are you able to send a screenshot?
The error message was as in the title, it appeared into the chat window. I think was a remote connection issue of a contact, because I’m able to chat with other contacts normally
