Your network setup seems to have issues. Find out why 192.168.x.x is unreachable. Is this address correct in the first place?

Also find out if is correct and reachable, and the MySQL port is open on that server.

I corrected the problem by uninstalling rabbitmq-server

apt remove rabbitmq-server

apt purge rabbitmq-server

apt install rabbitmq-server
