I’m running into an issue installing the secondary/subscriber Unity Connection (CUC) server at a client. It keeps on failing the validation and not allowing me to continue:
I have removed and re-setup the server on the Primary/Publisher CUC using both hostname and IP address 3 times now to no avail. I can ping the server being installed from the Publisher/Primary without issue. Other Pub/Sub servers between the subnets installed without issue.
Does anyone have any thoughts on what I could try next? Has anyone seen this before?
Any help much appreciated!
Solved! Go to Solution.
I had same problem and fixed with above roll back solution but it didn't validate and give error "could not connect publisher via tcp port" so I tried third time and then it worked.
Here we are 5 years later and I ran into the same issue installing UCCX 12.5.
After 2 days of working with our network team and getting different IPs and DNS records created I did the steps you mentioned and after the second attempt it WORKED!!!!
