Describe the bug
Hi, first of all english is not my main language so sorry for misspelling,
so heres my setup:

Server with Docker installed - IP 192.168.2.3
Docker Network 1 - 10.0.3.0/24
Docker Network 2 - 10.0.10.0/24

Nginx Proxy Manager is connected to both Networks and can ping everyone.
All already ceated Hosts are in Network 1 and are working.
My latest Project should be seperated from the others, therefore the extra network.
From the Nginx shell i can ping the container in network 2.
From local Network i can access the Webinterface via 192.168.2.3:1234.
But the created host with following settings:

domain: "test.mydomain.com"
sheme: http
forwarded IP: 192.168.2.3
forward Port: 1234
cache assets, block common exploits, websocket support off (for testing)
no settings in custom location, ssl or advanced.

This host is not accessible via the domain name. It just drops an 504 Gateway Time-out.
Every other Host is reachable via SSL (i also testet the Container above via SSL and its the same error).

error.log:

Nginx Proxy Manager Version
v2.9.18

To Reproduce
Steps to reproduce the behavior:

  1. Create a new Docker Network
  2. Create Docker Container and add it to the new Network & NPM too
  3. Create a CName for the new Container and create the Host
  4. Open the Webinterface of the new Container via IP and it will work.
  5. Try to open the Webinterface via the CName specified in the Host & See the error

Expected behavior
Simply work ;D

Operating System

Hi @Scarpall, where did u make this change?

Did u make the change in the Forward Hostname / IP input field for the proxy host? If yes, have you tried using the docker container name?
