What’s your point?

[Peter Doornbosch]

My point is: this is not a bug. A socket timeout can happen if your server is not sending data during the time you let the plugin wait for it. It’s similar to you expecting a phone call. You are waiting for it, but the phone doesn’t ring. This does not mean the phone is broken (although that is possible of course ), the most likely explanation is that the person did not yet call you.
