This is our old Q&A Site. Please post any new questions and answers at

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 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

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?
