I have a UCM6.1 running and I'm trying to add the first new subscriber. During the subscriber installation after I'm asked about the "first node" IP and other details, I get a error message: "this is not the first node". I am very sure about the IP address and Hostnames. Note:I'm not using DNS nor NTP. Note: Publisher can ping the new half-installed Subscriber. I've got 2 nodes licensing. What is happening? Is this a bug? Should I use DNS? Any help will be 5 point rated.
