Can't connect to the UDP tracker

[josecelano]

Relates to: #14

I'm trying to make an announce request to the UDO demo tracker, and I get a timeout error:

cargo run --bin udp_tracker_client announce udp://tracker.torrust-demo.com:6969 9c38422213e30bff212b30c360d26f9a02136422

Error:

Error: Failed to receive a connect response, with error: Timeout while waiting for the socket to become readable.

It could be related to #14

I'm going to try increasing the client timeout.

I can sometimes connect:

$ cargo run --bin udp_tracker_client announce 144.126.245.19:6969 9c38422213e30bff212b30c360d26f9a02136422

  }

The problem could be the server is busy, but it does not look so:

In fact, it's strange because the server was restarting regularly when the memory was full, and it seems that's not happening now. It could be related to #14. Many announcement requests are rejected because of an invalid connection ID.

I'm going to close this and try to fix #14 first.
