psql: error: could not translate host name "matrix-postgres" to address: Try again

[TheRedTopHat]

This error occurs during the matrix-postgres : Execute Postgres additional database initialization SQL file for synapse play. The error output is below. It first appeared when I added the necessary options to vars.yaml to install dimension, as outlined here. I have since commented those out, thinking they may have been causing the problem, but the error persists. Happy to provide any additional output needed, any suggestions are appreciated. Thanks!

Hi. Have you had any luck with this? I'm getting the same error on arm64 following the directions here https://matrix.org/docs/guides/free-small-matrix-server

I'm facing the same error. I never had Dimension enabled so, doesn't seem to be related to that? I'm using fedora 36
