[SR-Users] Playing with Diameter - Error opening connection to :3868

Mon Jan 28 15:54:15 CET 2019

Yasin,

Thanks for that... I was thinking the DNS possibly. I can nslookup the 
FQDN fine at the cli of the server and that returns the correct IP. I 
will concentrate on the DNS and have a play.

Thanks,

Steve
