Webtop work on LAN but not after reverse proxy

Hi, i have a functional Webtop docker, which work ok on LAN.
Also in LAN i have multiple http/https services reachable from public internet with Nginx Proxy Manager.

I’m pretty sure the config on NPM is ok due the website open, favicon load, and black circle load aswell. But nothing else.

From internet if i do VPN i can see it propely (at the end the VPN get me on my LAN) so the problem is not at the remote viewer device.

Webtop runs under RPi 4. Any idea?

We don’t offer any support for NPM. It would be best to seek help from the devs/support of NPM if any exists.

Thanks but is not a NPM config issue, i have 20+ Proxy Hosts and this is the sole that do not load correctly from outside LAN.

As commented on LAN is ok, but over WAN only favicon and dark circle load, the rest of assets at Desktop do not display

Please provide the compose or run snippet for webtop and full container logs (they begin with our ascii logo)

If nothing stands out in the logs/compose, then for testing, you can port forward 3000 from your router to your docker host and show the dev console output when connecting from the WAN to your webtop instance. To accomplish this, i would suggest limited the source ip to that of your mobile phone when not on wifi, though whatever you feel safe doing is fine.

I found a clue on what the problem may be. On LAN i access webtop via IP, on WAN i was accesing via domain name. If over WAN i use my public ip address instead of domain name, Webtop load OK.

I’ll try modify hosts file for Webtop to know this domain name is himself. Thanks for support!
