so I can't seem to send emails and this is the only error in the mails worker

TL;DR

SMTP is failing with a Mailgun error related to authentication. The Redis error mentioned seems to be unrelated. The user has checked SMTP variables and they are set correctly. They can successfully send emails using the same credentials via command. The problem could be due to a self-signed certificate. The user confirms that the Mailgun credentials are correct. The user provides logs showing Redis errors and a permission denied error related to the Docker socket. They suspect a problem with the server. The Redis connection between the container and Redis is identified as the issue. The user also shares additional environment variables related to SMTP. Possible solutions: - Confirm that all SMTP variables

weird....this seems to be a connection between the container and redis 🧐

can you check the env vars and make sure they're set correctly in the container?

yeah seemingly happened all of the sudden

lemme check

TypeScript

_APP_SMTP_HOST=smtp.mailgun.org
_APP_SMTP_PORT=587
_APP_SMTP_SECURE=tls
_APP_SMTP_USERNAME=support@mg.pva.ai
_APP_SMTP_PASSWORD=my_password

This ones extra weird yeah I agree, I can give you access if you need

no no. it's not a SMTP problem. It's a redis problem

TypeScript

_APP_REDIS_HOST=redis
_APP_REDIS_PORT=6379
_APP_REDIS_USER=
_APP_REDIS_PASS=

TypeScript

permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/519ba1fee0d9/json": dial unix /var/run/docker.sock: connect: permission denied

in the redis-alpine

that's weird...redis shouldn't need the docker socket..

just restarted

orrr this might be a problem with the server 🧐
