Notifications not working

[thebigjoe1]

Below is my docker compose file. Can anyone tell me if I've done something wrong with respect to gotify/email notifications? I have an .env file for everything, which has served me well with other docker projects. I don't see any error in the logs or any mention of gotify/email notifications int he container logs. Any help is appreciated.
