[solved] Internal server error when setting custom domain

(This was built using the Linode marketplace instance automatically) I'm not going to use my actual domains for this, but I have the Appwrite panel set up at backend.example.xyz, which is the value for both the _APP_ENV and _APP_DOMAIN_TARGET environment variables, but when I try setting a custom domain for a web app to something like api.anotherdomain.me, I get an internal server error popup

TL;DR

The user was experiencing an internal server error when setting a custom domain in their Appwrite panel. They realized that they forgot to apply changes to their .env file by recreating the containers. The error message indicated that the CNAME target was unreachable and advised using a domain with a public suffix. The user asked about the docker logs for the appwrite container. The issue was solved, and the user thanked everyone for their help.

What do the docker logs for the appwrite container say?
