Example Error
The following is an error received when Exporting your Design from the Cobwebb Designer using sockets
Failed to Create Data Channel, Error Code is: 100xx
Reason - This was because port 3772 had been unblocked but port 3773 had not. Firewalls etc. need both ports (3772 & 3773) unblocked for Cobwebb Designer Export to work when the Use Sockets Server option is used. The PCSRVI (SOXSVR) job, running in the CPPD Subsystem, listens for connections on port 3772. When a file store request is made, a separate connection is created on port 3773.
