-> In my case, there was a network issue wherein the nodes were removed from cluster due to quorum loss and then came back online automatically. But the Always On Cluster role went down as shown in below screenshot,

-> I was sure that Cluster was online and also that the nodes are all available. I right clicked on Role “JBAG12” and clicked on “Start Role”. it came online without issues,

-> Availability group came online and everything was working fine,

Thank You,
