~~I'm ending up with the same problem on a 1.2 STABLE release.
I have:
both machines up-to-date usernames the same passwords the same firewall rules on the SYNC interfaces on * * * *I also rebooted both machines, but this gives no clue.
HTTPS or HTTP set on both machines doesn't make any difference also.
What could be wrong here ?~~
I have solved this issue. It should have been a subnet that needed to be test on /24… this was also in the second trouble shooting part.
