SAS/Share ERROR: Invalid object specifi...

Had an interesting error message today (SAS 9.3, Windows 2012R2), which appeared to be truncated:

ERROR: Attempt to connect to server "dev01.domain.com".__8551 rejected by server.
ERROR: Invalid object specifi...
ERROR: Error in the LIBNAME statement.
The issue occurred when trying to connect to a SAS/Share library using the following syntax:
LIBNAME MYLIBREF REMOTE  HOSTNAME="dev01.domain.com"  Server=__8551 slibref=MYLIBREF;
The fix was simple - simply log into the application server, open Services, and restart the "SAS Share Server" service.

This left the customer happy, but I’m still curious about what caused the elipsis (…)

Any ideas
