Appwrite Server 404 Not Found

Someone help please

I'm using docker appwrite on my vps hosting server. there are other projects running on nginx as well so to avoid issues i'm using nginx server configuration to run appwrite as well. I made some changes on my other projects (not nginx) but once i go to my appwrite domain, there's this login page. it was logged in before. after i login it throws this 404 error.

I already have taken backup using a script. It takes backup of docker volumes, storage and important stuff then there's a restore script

Then archive using another script and use restore script to restore the backup. if it's not an issue with docker itself. that shouldn't cause a problem right?
