I was able to play SC yesterday but when I try to play today it appear the message

Your internet conection is either very poor or is not processing UDP packets through port 6112. You will able to chat but not be able to play games. Contact your internet service provider or your system administrator for assistance with opening this port...

I simply haven't change any network setting of any kind. The problem have happened before about 30 March and it go away about 15th April.

I have tried re format my computer and do the fresh install and the problem still exist. Is there any network setting change on the server side ?

Thanks

I can't pinpoint the issue has I really don't have advance knowledge over the Starcraft Server. However, this has happened to me as well in the past two weeks a little mor frquently. I believe the server come in and out. Its not your internet rest assured its just the server, client bugging out is the only logical conclusion I can find out. It happened to me yesterday and all I had to do was log once or twice to get working.

Hope this helps at all.

Maybe there are changes from your ISP side on your network and they could have closed the ports. Can you check if they are opened?

I have already checked with my ISP side. Nothing have been change. Every thing is the same including my IP address. It seem like the return packet for checking port 6112 is missing when I log on to the Bnet (ICCUP) server.

This problem seem to happen before www.iccup.com

some of the user seem to have same problem like mine. I believe during that time some thing have been fixed

on the server side and the issue is gone but now it is happening again.

I do have the tracert and packet tracer files that couild explain the problem if the admin need that.

Thanks

Closed.
