Comm errors are all related to the communication of the system. Try to check if the firewall permits the software to communicate with the Internet. Alternatively, ping the server you want to connect because there could be problems with the remote IP. Usually COMM errors are ambiguous, meaning that don't have a specific fix and the cause that makes them appear are various but they're all related to network communication. Check all the network components and make sure that everything is working find. Perform ping and traceroute operations on the target IPs.
