Nginx addon appears reset/new, but everything still working?

I’m running Nginx as an addon in my HA install. I normally access HA from the domain I’ve set, but I had to go to my local IP to access the Nginx webui. I haven’t done this for months, and today I went to add a new domain and it didn’t take my username and password I set for Nginx. It took the default username and pass instead, and upon logging in there’s nothing to look at.

And yet, I can still access all my domains (I think I have five of them). I’m certain I’ve been depending on HA’s Nginx. Any ideas?

If I stop the addon, I immediately lose access to HA via remote, as well as all my other domains. So it’s still somehow, magically running all my stuff yet when I log into nginx it appears as if I just created my first user. It’s been running for over a year! I am at a total loss as I cannot edit my existing reversed proxies.

It’s probably this: top issue on their github
