Answer 1

TL/DR: Check the master IP address and try to run with the updated master address.

Reason: if you have stopped your instance previously and if you have restarted the instance then the master address is changed but the slave agent has the previous Jenkins IP itself. so check the master IP of Jenkins master and modify it in your command and then try to execute it then this will work for you.
