Yes, the final setup would be to run Adguard on a docker container and have this container be in a VPN. I’m not sure yet, how I would do that without messing up the other things already running on that VPS. Maybe I will go for Raspberry to run adguard at home.

Edit: I have set the second DNS in Windows to the same IP, so it shouldn’t have a fallback.

Solvena OP ,

thanky you, this looks like exactly what I need.

I do run several webservices (nextcloud, matrix) behind the same reverse proxy (nginx prxy manager). In my setup I have one docker with nginx running, which is the only one to be exposed to the web. It proxy-ing for the other services relies upon them being in the same network. It all works well, however I ran into problems when restarting my server after a shutdown. I suspect that some of the services tried to get the same ip adress as my nginx service, which results in that service not running properly and my whole reverse proxy setup falls apart at that point.

I’m not certain, that this is really what happens but I want to try and assign the fixed ip’s and see if that solves the problem.

Solvena OP , (edited )

Edit: I fixed my problem by re-making my nginx reverse proxy and a do-over of my proxy hosts. I have yet to restart my server, though …

I’m a beginner with all of this stuff, so I’m sure I’m not assessing correctly what’s wrong with my setup. It’s more of a methodical “trial and error” approach, that I have, where I change one thing at a time and see what happens … quite time consuming but it helps me to figure things out along the way :)

However, if you have an idea, what could be wrong with my server, I’d appreciate any ideas: I run Nginx Reverse Proxy with nginx in a container within a custom network “my_network” and have assigned that container a fixed IP. I run other containers (portainer, mariadb, nextcloud, synapse) that all connect to the same custom network. The nginx container “see’s” the outside web with ports 80 and 443 openend on the firewall for that container’s fixed ip and routes traffic (and needed other ports) to my other containers. This is all working well and also works after restarting the server.

Now I tried to install a lemmy instance and got it up and running by bringing the lemmy containers in my custom network as well and proxy’img my nginx to the lemmy proxy. However, when I made a restart of the server, something broke and I cannot get the web-ui of NPM to load. I think somehow host names and/or IP adresses got mixed up somewhere. The containers start just fine, but I can’t access it with web-ui anymore. Also reverse proxy-ing doesn’t work, but if I open the needed ports on my firewall manually I can access the other services containers.

I hope this is even understandable, not sure if I’m using the correct terms …

Solvena OP ,

In the configuration of the docker proxxy, do I define my domain name (like lemmy.my-domain.tld) or will I define some local IP (like 172.20.0.1) and let nginx proxy manager point to that?

Solvena OP ,

Which domain name should I put in the nginx configuration from Lemmy? My intended domain (like lemmy.my-domain.tld) or do I put some internal IP (e.g. 172.20.0.1) and point to that IP from my host nginx?

Solvena OP ,

thanx! I got it running now, not sure yet if federation is working, but at least I have my instance up and could register admin + standard user :)

Solvena OP ,

This makes it clearer to my, would you mind helping me to understand all steps for my usecase. I want to run a lemmy instance and a mastodon instance on the same VPS, using the same domain but different subdomains - lmy.my-domain.tld and mstdn.my-domain.tld. I have my VPS IP address and setup the 2 subdomains with my domain provider (both subdomains are resolving the same IP).

I also did setup nginx on my server and can install SSL certificates for both of these domains. I’m now at the step where lmy.my-domain.tld should by directed to the lemmy service and mstdn.my-domain.tld to the mastodon service. As I understand it, both services listen to the ports 80 (http) and 443 (https). Do I now setup a room/building for Lemmy / Mastodon respectively where I tell nginx that lmy.my-domain.tld is at 0.0.0.0:3001 and mstdn.my-domain.tld is at 0.0.0.0:3002 for example. And in the config files for each of these installs I’d specify “0.0.0.0:300x” respectivly? (also have to make sure, that these docker installs don’t mess with my nginx config by themselves, right?)

Solvena OP ,

Could you have a look at my answer to the poster above - would multiplexing mean, that I configure my internal IP 0.0.0.0:XXXA for one service and 0.0.0.0:XXXB for another?

Solvena OP ,

thank you, that clears things up a bit. Now it’s to play around with it, until I get it up and running :)

[Question] Installing Lemmy instance from docker -> 502 bad gateway

Hi, does anybody have an idea what the reason could be? I installed a lemmy instance on a VPS using the docker images. Beforehand I installed nginx and got a letsencrypt - certificate (which seems to have worked). I downloaded the nginx.conf file from github and made the configurations, also in the lemmy.config and...
