Hey guys, I have nginx proxy manager running in docker container on my home server. I don’t have any ports open (other than wireguard) and I was using custom local domain .tride to access my services. Everything works fine, I can use https://portainer.tride, https://homeassistant.tride, etc.

I want to get rid of warnings about the risk that I have to accept to continue. Not a big deal for Firefox on desktop, but its kinda annoying on Android. Also I think it stops me from using some services that require SSL certs (like floccus). I tried to create a LetsEncrypt certificate using DNS challenge and DuckDNS in NPM. I also tried to download certs and import to Android, CA cert is added successfully, but didn’t work.

Now I bought example.com domain from porkbun.com and trying to set it up:

  1. Created CNAME on porkbun - *.example.com pointing to my example.duckdns.org
  2. Created cert using same procedure (DNS challenge and DuckDNS in NPM) with hosts *.example.com and example.com
  3. Created Local DNS records in PiHole

Now I get strange behavior, sometimes I can open portainer.example.com with no problem, no warning, perfect. Then sometimes it doesn’t load at all and it says “Server Not Found”. Some services open normally, but like bookstack.example.com opens broken page and if I click anywhere it redirects me to my old bookstack.tride (still exists in NPM and PiHole) and asking to accept the risk.

I’m trying to use services from local network or wireguard only, at least for now.

I am also using the same domain for my e-mail at mailbox.org if that matters. Not sure what I’m doing wrong, but I’m sure there is something. I’m happy to listen any suggestion, and sorry for being noob <3

    I use nginx proxy manager with dns challenge to get a *.example.com cert that I then use to host services internally. I just checked, it supports dns challenge for porkbun, you may want to give it a try again. Also, you shouldn’t really need to forward dns to duckdns. You can have public dns records point to an internal ip.

    This is what I do, I have example.com (dns registered with cloudflare but should work the same with porkbun) I then create an a record for portainer.example.com to 192.168.0.5.

    Internally my nginxproxymanager is running at 192.168.0.5 and portainer is running at https://192.168.0.6:9443

    Then in nginxproxymanager I create a dns challenge (you’ll have to look up some videos on how to do this, it’s not very difficult it usually just takes a api key and secret key) then I create a new proxy host for portainer.example.com pointing to https://192.168.0.6:9443 and you select the *.example.com as your ssl cert for the proxy host

    Now internally go to https://portainer.example.com and it should work.
