I updated my incognito iOS app to v3.6.3 and my self hosted vNodes no longer show that they are reachable, and the "Fix It’ now appears. Both nodes have earned PRV last week, so they were online. Docker ps shows they are online, and they show activity on network/cpu/disk plots.
I am not quite sure how to debug the issue and would appreciate any direction/feedback.
Also, while I know its not official, mesquka tool does connect, and I am able to query both machines with my own scripts to get status and public mining key (if that is of any use for debugging the issue).
