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

    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

      thank you very much for your config file, however on pasting it and running it, i get the error

      ERROR: The Compose file './docker-compose.yml' is invalid because:
      Unsupported config option for services.caddy: 'lemmy'

          thank you, the config now runs, unfortunately i am now getting a bad gateway when visiting the website. Also in the logs i see two errors that catch my eye thread 'main' panicked at 'Failed to load settings file, see documentation (https://join-lemmy.org/docs/en/administration/configuration.html): LemmyError { message: None, inner: Is a directory (os error 21), context: SpanTrace [] }', crates/utils/src/settings/mod.rs:20:20 and caddy_1 | {"level":"error","ts":1688725909.314515,"logger":"http.acme_client","msg":"challenge failed","identifier":"lemmy.emphisia.nl","challenge_type":"http-01","problem":{"type":"","title":"","detail":"","instance":"","subproblems":[]}}

          Also according to portainer, no ports are open on the caddy server. I have never used caddy. Thank you btw for trying to help me :))

            Oh shit, I forgot that your Caddy would be running on a bridge network by default because mine is on the host network where all ports are already exposed to it! (It’s generally a bad idea to use the host network, so don’t do this if you’re only using Caddy with containers on the same network) I edited the Gist to expose 80 and 443 for HTTP/S on that container, the updated file uses the same Github link. Really sorry about that!

              I actually need the website to be hosted at 8085, as the nginx reverse proxy is listening at that adres, and it has already bound to port 80 and 443. When i open internal port 80 to 8085 and set the lemmy port to 8086 in the compose file. when i then visit the site i get a redirect loop. (im probably doing something horribly wrong). Also lemmy keeps panicking

                Why do you have to use NGINX? Caddy does the proxying to the Lemmy containers for you. That docker-compose.yml file is my entire deployment, there is no hidden NGINX container or config file that needs to be added. Just remove your broken Lemmy deployment with docker compose down and delete the containers, then docker compose up my docker-compose.yml (after you edit the postgres variables) with config.hjson in the same folder.

                  hi, apologies for the incredibly late response, i was on vacation. So as per the setup guide of lemmy. i am using two nginx instances. one i a lemmy internal nginx, running in a container which uses the nginx-internal config file. This exposes lemmy on port 8085. i then want to use a reverse proxy so that i can access the website on lemmy.emphisia.nl for that i use a second nginx running on the host machine. this one is the reverse proxy for all services i have running on the machine. (nextcloud, onlyoffice, bitmanager and lemmy)
