Can't access Paperless-ngx via VPN (reddthat.com)

Hi, I have a problem accessing Paperless-ngx when I'm connected to my home network from a VPN. I've tried to make a simple sketch of my setup: Phone --> Wireguard --> Public Internet --> Unifi Wireguard server --> Home Network

Paperless-ngx is hosted on my server at 192.168.1.10:8000 But I can easily access all other services hosted on my server (192.168.1.10), e.g. homer (:8888) and Immich (:8080). It is just Paperless-ngx which doesn't work.

When at home and connected to my home WiFi I can also access Paperless-ngx.

Anyone having ideas to figure out, what is wrong in my setup? Or how to debug?

Your WG network is a separate subnet. Add it to PAPERLESS_ALLOWED_HOSTS to allow access.

Without having time to test it yet, I think this is the issue.

Ping,Tracert,Knock on the port with Telnet.

I’m guessing firewall rules related to your vpn.

Ping and traceroute are both successful. The IP is not the issue (I think), as all other services on the same server are working fine According to unifi firewall logs, nothing gets blocked when I attempt to access Paperless-ngx.

Can you hit the port?

I’m not familiar with paperless but do you have PAPERLESS_BIND_ADDR set? maybe try to set it to 0.0.0.0

It must be a Paperless-ngx specific issue. Stopped Homer service available on :8888 and changed Paperless-ngx to be served on :8888 and it still doesn't work. This rules out firewall and network issues as Homer was accessible on this port.

What's in the logs?

[–] StreetKid@reddthat.com 1 points 2 weeks ago

Nothing in Unifi firewall logs nor Paperless-ngx logs. I'm using standard zones based a firewall rules in Unifi. And I looked through the firewall rules, and I don't find anything related to port 8000.
