Lemmy on Docker - Postgre Authentication Fail (waveform.social)

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!

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.

I tried this... updated the user to lemmy1. The error message does indeed change to reflect the new user.

Super frustrating!
