I’m trying to get Lemmy up and running on an Ubuntu 22.04 host. I’ve followed this guide supplemented by googling.

I can actually get to the front end, but it gives me “There was an error on the server.” When I dig into the logs, I see this:

"thread 'main' panicked at 'Error connecting to postgres://lemmy:<my pg password>@postgres:5432/lemmy: FATAL:  password authentication failed for user \"lemmy\"\n","stream":"stderr","time":"2023-06-26T03:14:17.47460915Z"}

The only thing I can find about this error related to Lemmy is this thread, which indicates that the password was not defined in the docker-compose.yml file prior to starting the containers. I have since redone the configuration three times, each time deleting the volumes folder and double-checking that my postgre password is correct both in docker-compose.yml and lemmy.hjson.

Any ideas what might be the problem? Thank you kindly for any help you can provide!

    Yeah the name you want for the database host is postgres, or whatever the container is named in the docker-compose.yml.

    I was curious about this, and it turns out both work. I tested by pinging both postgres and lemmy_postgres_1, and both responded with the same IP address. Good to know, but I did go ahead and change it back to postgres

    Maybe try a very simple password temporarily like test, rebuild the postgres container/delete the volumes and see if it works.

    I did this, and I’m still getting the same error, so obviously something is wrong.

      At this point it makes me wonder if your changes are making it to the containers. If you change the username for the db both for postgres and lemmy, do you get a different error about the new username? Maybe lemmy’s just using the default config and not reading your hjson file, that’s a good way to test that.

      Otherwise I’m at a loss, it should be pretty simple.
