The FD cannot connect to the SD IP/port

Common Solution:
Please make sure you can telnet to the IP and port from the FD to the SD along with telnet from SD to FD port 9102(check any routes and firewall configs). If LAN IPs are in use, make sure to utilize these via telnet checks. You may want to restart service on both the FD (Linux: service bacula-fd restart or on Windows: restart the service) and SD (service bacula-sd restart) before starting the new Job and monitoring it.
