When system coupling run fails with error:

"*** ERROR ***                           CP =       0.078   TIME= 13:31:29
 MAPDL is unable to connect to the system coupling service on XXXX through port #####.  Check the -schost and -scport options on the APDL command line in the System Coupling analysis and ensure that the host name and the port number are correct. "
 
The workaround is to set this environment variable before starting System Coupling:
 ANSYS_RPC_LOCALACCESSONLY=1
