As a side note, how do people handle HTTPS with private networks (VPN or local) these days? I typically just stick to HTTP, but it would be nice to get rid of the warnings/lock (and I use HTTPS-only mode and firefox seems to require a fresh exception for every port).
I’ll throw in SWAG as another option which I found was easiest to setup, albeit it on a VPN/local only setup. It supports certbot for SSL and pre-defined proxy configs for various services (mostly linuxserver.io containers but there are others) and it’s easy to edit them to make your own configs. I’m not sure about portainer support as I’m not familiar with that.
