Hello all. I've just decided to place my two MWG instances back into a cluster setup in order to have them be synchronized but I've been hitting an issue where it said "cannot add node because local node has no running listener available". I saw a post on here saying that that error message was misleading and was really an error due to changes made in 7.7.2 re: Cluster CA settings.
I then proceeded to follow the "Replace the cluster certificate" instructions in the 7.7.2 Product Guide, exported cert and private key to a file. After that I imported the exported CA cert to both appliances. When I add my second appliance to my first appliance, I see this error:
I also see that the second appliance is intermittently unreachable. I'm not sure why this happens. it's the same case when I use a CA cert from our enterprise CA. Could anyone assist?
I'd suggest checking the listener address under Configuration > Central Management, in some cases the listener might have a different IP than what the appliance owns.
For example, the IP of my appliance is 10.1.1.6, but the Central Management Listener is set to 10.1.1.7:12346. MWG will try to bind on that IP, but fail because it doesnt own the IP.
Thank you for your reply, Jon. I had previously checked the IP address and both inside Central Management and Network Interfaces have the same single IP address.
