Detailed description of a problem

I attempted to create an automated reward collection bot, but after the program has been running for a while, it encounters the following error and is unable to continue running.

What did you try yet?

Did you try any method from the API?
yes
Did you try any example? Any error from those?
yes

Then

Timed out get 6 createBot <Thread(Thread-2202 (loop), started daemon 140287095662272)>
Timed out accessing 'quit'

and

Timed out get 6 createBot <Thread(Thread-2202 (loop), started daemon 140287095662272)>
Timed out accessing 'createBot'

Expected behavior

No such error occurred; it continued to function normally.

Additional context

If you need my code, I will provide it.
Thank you very much for your assistance in resolving my issue.

This is likely a problem on the server. Can you reproduce on another server?

[watercatlxh]

I think so, that server is using custom packets, so is there a way to implement an action that ignores some packets?
