I am a newbie at Azure and this is my first question at StackOverflow. I have a problem on deploying new Azure App Service with Multi-Container Docker (Linux) using Docker Compose. Unfortunately, I can't access my application log because there are unknown errors. I only change the configuration to use my private registry and docker-compose configuration, other settings stay at their defaults. I am using Azure for Students plan so opting in to 1:1 expert support is not an option.
My app services basically consists of 4 containers: webservice (Django REST Framework), comprof (VueJS), raspisample (Express), and db (PostgreSQL). I am using GitLab's Docker Registry (registry.gitlab.com), and it is a private registry (images aren't available publicly). Here are my docker-compose.yml file.

This docker-compose configuration only fails at my Azure App Services. I have another VM at my college and this configuration works fine there. I also tried at my own laptop and it also works fine. At Azure, here are the error message:
:( Application Error
If you are the application administrator, you can access the diagnostic resources.
When I try to troubleshoot this problem on the app settings > Container Settings > Logs, it shows me this one line error:
Error in retrieving logs.
I also retrieved same error when accessing log via Log Streams. I have enabled Application Logging on App Service logs menu, but it has no effect whatsoever. I also can't access Azure's suggested link to Docker logs, it just loads forever and returned connection timeout error after 15 minutes of loading.
The question is: is there anything wrong with my docker-compose.yml? Or is there anything wrong with my Azure App Service's configurations? Thank you.
