Local IP for accessing Nextcloud

[TJB88]

Very happy with your instructions and it is working great. I can access it anywhere with my public duckdns-URL but not from inside my home network.
It seems it will be caused by a NAT loopback, which cannot be resolved with my ISP. Do you have instructions how to make it accessible from inside the home network? My server runs a couple of Docker images and has 192.168.1.3 as static IP.
It would be great to access Nextcloud from 192.168.1.3:8081.
I tried adding the following tothe Nextcloud-app part in the docker-compose, but not with the desired result. (Sorry noob here).

ports:
      - 8081:80

I have the same problem myself, It's to do with the proxy setup, but I have never looked at fixing it as it's not bothered me, and I'm not really sure how. I'm lucky enough to have a stable internet connection, so just access it through the public URL. I'll leave thi sissue open in case anyone else figures it out.
