Hi, not sure how to delete this topic so I’ll just post the issue and solution here:
I was setting up this new node inside of a windows Azure cloud service which only contains the existing couchbase node that I’m trying to connect to, and the new node I just created. I didn’t check the internal IP address of this new node properly though, and so the IP I had on the config screen for it didn’t match the actual internal IP address. Once I fixed the IP address I was able to connect the servers. I also uninstalled couchbase 2.5.1 and installed couchbase 3.0.2 on the new node instead, though I’m fairly certain the issue was with the IP addresses not matching.
