Sockets closed when playing games

0

I've been having this issue lately where I am playing two games(EVE Online and Diablo 3) and at random times for EVE Online I will get the error that the Sockets were closed and for Diablo 3 I get Error 3007(Which happens at the same time)

The customer support of CCP told me that when sockets close it means I was unable to send or receive 5 consecutive packages. Error 3007 can occur when a computer is unable to maintain a stable connection to the Battle.net servers.

When this occurs I don't seem to loose internet connection. I ran Wireshark and close to the before receiving error 3007 I sent out an ARP to the address of my modem. Shortly after I sent out an TCP (RST, ACK) package and lost connection.

I also get allot of TCP Retransmissions close to when this occurs.

Is any of this related to eachother?

I would be very grateful if anyone could help me in resolving this issue!

Thanks in advance

One Answer:

This looks like the client has exhausted its retransmission retries and therefore closes its socket after not having received an ACKnowledgment from the bnetgame server.

So, to answer your question: Yes, the retransmissions and the RST packets are related.

Why don't you get ACKs back?

  • either the server never saw your segments as they were dropped in the network
  • or the server saw your segment and did not respond to it (dropped it internally)
  • or the server sent the ACKs and they were dropped in the network

Not an easy task to figure this one out - from a client's perspective

I see. You have any idea what could be causing this?
