The handshake/read operation timed out

[Jerrk]

I've started running into an issue lately where trying to scan-client on deluge will time out after about 10 minutes.

Its running against over 6k torrents so there might be short hangups now and then but it seems at2 will time out the connection and break the scan.

heres the verbose error log

Appears to just need a bit better error handling to skip the entry that it timed out on, increase the timeout timer, and/or retry the entry.

Very similar thing on qBittorrent.

My guess is that the client is working too hard which makes the API too slow. The only solution is to make autotorrent wait longer.

Not sure if that just puts more work on the torrent client or what. Not really sure what the solution is here.
