For testing connectivity between the client machine and the machines of your compute cluster, you can use Admin Center. For more information about Admin Center, including how to start it and how to test connectivity, see Start Admin Center (MATLAB Distributed Computing Server) and Test Connectivity (MATLAB Distributed Computing Server).
If a worker cannot resolve the hostname of the computer running
the MATLAB® client, use pctconfig to
change the hostname by which the client machine advertises itself.
If a worker cannot open a socket connection to the MATLAB client, try the following:
Use pctconfig to
change the hostname by which the client machine advertises itself.
Make sure that firewalls are not preventing communication between the worker and client machines.
Use pctconfig to
change the client's pmodeport property. This determines
the port that the workers will use to contact the client in the next
pmode session.
