Nginx proxy manager is not being able to serve the page from another docker container

I am trying for nginx proxy manager (running in a docker container) to connect to another docker container that has port 8080 open on it. When I setup the proxy to connect to 192.168.0.29:8080 the ip address of the host, but it doesn't work, the browser just says that the site didn't send any data.

I tried setting up the reverse proxy with other services (that weren't running inside a docker container), and they worked flawlessly. So, I've concluded, the problem is something with the docker containers.

First, I tried replacing the ip address with the address of the container (shown in portainer) which showed to be 172.17.0.2. But, that didn't work. I can confirm that both containers are in the same network, bridge.

I could not find any solutions for this problem either here, at Stack Overflow, or anywhere else. Hope there's enough data to solve this problem. Thanks ahead of time!

Edit: running arp -na from within the container gives this output:

[root@docker-00244f7ab2cc:/app]# arp -na
? (172.17.0.1) at 02:42:d1:fc:fc:6b [ether] on eth0

I found the solution to my question after lots of searching and testing and it's quite simple. The solution is to start the nginx proxy manager docker container on the host network instead of the bridge network. Then, you can use localhost and then the port to refer to which service you want to redirect to.
