The only solution I found was to reinstall the nginx proxy manager addon. Your current config should still be saved in mariadb addon.
updating to 0.12.2 didn’t fix the issue either.
I did have to muck around with the proxy host address after reinstall to get it to find my local hostname again. I had mypihostname.local set. I was getting sent to a HA loading page with a 60sec retry timer. I set my local host back to IP number and clicked the external link from proxy hosts page.
I swtiched it back mypihostname.local after that and it worked fine.
Although in hindsight, that is probably a unique issue to my system and how it handles dns.
