I keep getting this error every time my IRC bot is connected. This just started happening this morning after running this bot for over a month now.
Additional information: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine.
What would be causing such an error?

InnerException:
Typically this happens when you get disconnected. That can be for a variety of reasons, but often it’s because you aren’t responding to server pings in a timely manner, or your message buffer isn’t being cleared fast enough.
See I find that very weird. Like I said this has been working for a month no problems what so ever. It doesn’t seem to be happening anymore. It’s not like it is under a heavy load. It’s actually very idle at the moment. I’ve looked on stack overflow and a few other websites. It says it could be my firewall killing the connection. So I disabled my firewall and this is still happening. I don’t know how to debug this.
I’m not sure exactly how to do that, but this hiccup was immediately terminating the connection so I’m not sure rotating the IP would have solved the problem. It is definitely something to look into though.
If it’s a firewall issue, or a server listener issue switching ips will connect with a server that is (theoretically) not impacted if it’s a transient issue.
Would you mind providing us with the IP that you resolve to when you connect to irc.twitch.tv?
Alternatively you can switch out (as others have mentioned) the hostname for the direct IP, which can help narrow down issues. If you cannot connect at all, it is possible your DNS resolver is returning stale data, which can be solved with "ipconfig /flushdns"
Websockets are a method of communication over a TCP connection, but you shouldn’t need them for your bot.
@xangold I didn’t check in time when the error was occurring. It started happening around 2AM that morning and seemed to resolve itself around 5AM.
EDIT: This is the IP I was resolving to. - RemoteEndPoint {192.16.64.45:6667} System.Net.EndPoint System.Net.IPEndPoint}
I went ahead and built in an IP rotatory into my bot and I have yet to encounter this error again. If you would like I can revert back to the old way I was connecting and provide you with the IP that it resolved to if the error would happen to happen again.
