Hey @LegiaP8741 from the error you encountering is a 'ReadTimeout' exception, which is raised by Netmiko when it doesn't detect a specific pattern in the output within a certain time period. You see the pattern is (?:R1.*$|#.*$), which is a regular expression (I had to decode that!) that matches either the string "R1" followed by any characters until the end of the line, or a "#" character followed by any characters until the end of the line.

This normally occurs when you device does not respond as expected, or when the command takes too long to execute. If you can reach the device by ssh from the host machine running the code ok, in the first instance, i would increase your timeoutout like this.

net_connect = ConnectHandler(**device)
net_connect.timeout = 60  # increase timeout to 60 seconds

Try this. Hope it helps. If you want, share your full code if the above does not work.

what is line 74, in <module> ? output = net_connect.send_config_set(commands_list_router)

I meant what is in command list ? what type of commands, etc?

take a look at ur commands_list_file and remove any notes, markings, remarks in ur command list file; Any inconclusive IOS commands; Add "!" between lines of commands if ur list is too long; also add time out 60 s mentioned above.
