[BUG] Connection lost about arrcon HOT 7 OPEN

This is definitely a bug; I'm not sure what could be the cause, however.

v4 will include a log (#18) that should help in diagnosing this issue.

from arrcon.

Please try v4.0.0-pr1 and let me know if the problem is resolved.

I will check this in due time. It'll be about a day for me to run some tests.

@radj307 I've ran some test with pr1 and got a error log for you. Hopefully it helps.

Authentication Successful.
Use <Ctrl + C> or type "exit" to quit.
RCON@server> save
[no response]
RCON@server> save
[FATAL]   Failed to read packet header due to error: "End of file [asio.misc:2]"! Flushing the buffer.

from arrcon.

The End of file error occurs when the socket connection has been closed.

What game is this? Some games (Palworld is one recent example) implement RCON servers with fairly short inactivity timeouts that may cause something like this.
Does the save command usually show a response? [no response] is a misnomer; it's shown when the server's response is blank (which is another thing that should be fixed).

from arrcon.

You guessed it. Palworld. And Save is indeed supposed to respond with Save Complete.

Yeah I was wondering the same with Palworld. You can only idle for roughly 10 seconds (at least it feels so) before the connection gets closed.
Maybe instead of just hard-cutting the connection ARRCON should have a setting that it tries to reconnect automatically when a command is issued and print that to the console. Or, if that would potentially break scripts, make it a command line flag (something like "ARRCON /autoreconnect").
