add the ability to interrupt the connection, when an unstable connection program may hang for a long time

Can you please elaborate on this?

could you ask questions more and more detailed

no possibility of interrupting the connection.
and the program hangs in an attempt to connect to the server - (push, pull ...)

What connection type you are using? If system SSH, then you have not configured it correctly.

i use http

and the problem lies in the fact that there is no possibility of control

I have posted the log
