The error "AMQ119007: Cannot connect to server(s). Tried with all available servers." is common since it comes up just about anytime a client fails to connect to a server for any reason.
Can you check anything listening on the configured port no.? Need to change the port from where it listens.
It may be simply network connectivity/configuration issues.
Check for DNS look up of IP address assigned by DHCP server whether it got expired? Check for the hostname value?
