Hello, I’ve been trying to host my own lemmy instance for a little while now but have yet to be successful.

I recently had my lemmy instance running but i could not find other communities, so i decided to remove everything and try again. Now however when i try to create an account or log in i get the error 404 for the file /api/v3/user/loginand nothing happens.

I’ve tried removing everything again and starting again but it is still not working

in the lemmy docker container i get the following error

edit: i just managed to log in, however the federation does not seem to be working. None show up in the communities tab and if i look for any communities i get no results and this in the log

    Hey, could you provide more details about setup? Are you using ansible or docker? Using any other reverse proxy?

          I am actually already running that config in the internal nginx, but i’ve never changed anything about it. what do i need to specify when they say “# this needs to map to the lemmy (server) docker service hostname” do they want the name of the docker container, and do they want the internal or external port?

            Yes, the hostname of a docker container is the name you set in the docker-compose file. IIRC the port should be the internal port.

            I don’t use NGINX as my proxy server, but it’s a bit strange that you would need two configs for this while mine runs perfectly with one config and two open ports (:8536 for Lemmy-BE and :1234 for Lemmy-UI). And why are you using different versions of Lemmy-BE (18.1-rc9) and Lemmy-UI (18.1-rc4)?

            If you are using the default docker-compose.yml on the Lemmy repo, that part of the NGINX config uses https:// + the name of the Docker containers. And you always give NGINX the external port (the number on the right side of the colon defined in ports:, like 1234 in 1234:5678). The port on the left is only known to the container the port is defined for.

            If it’s still broken after you correct the NGINX config, what are your docker-compose.yml and config.hjson like? There’s several versions of them floating around and you might have combined incompatible versions with each other.

              according to portainer, no other docker containers are using ports, so i don’t know what ports to set them as. I assume they are communicating over an internal network and the nginx is the only open external port.

              I am using two nginx servers because one nginx server is used by lemmy to give me one port to access. And the other one i use to set up my reverse proxy so that i can host more than one service on my server.

              I dont know why i have different versions of the ui and backend. I am just using the latest version avalible on the docker website.

              My docker compose file looks like this and the lemmy config file looks like this i got this config from here because i was looking for a way to correctly set-up my email because de documentation about the config file is really bad. But when using the default config file (found here).

                Yeah, the config file on the documentation sucks. I had to poke through several discussions on /c/selfhosting to find a config that wasn’t the extremely minimal one linked in the documentation. Your config.hjson is fine from what I can tell, although I’m not sure why you censored the hostname there as it’s supposed to be lemmy.emphisia.nl and not anything confidential.

                Honestly, I don’t have enough understanding of NGINX to debug its config, so I’ll just share my docker-compose.yml for leddit.danmark.party which worked correctly and federated out of the box, with a few adjustments to match your deployment. Note that you’ll have to tear down your existing deployment if you want to use this docker-compose.yml because they use the same ports.

                I should probably self-host my own pastebin
