Server error while adding custom domain

you definitely have to configure your domain to point to your server. Then, take a look at this: https://github.com/appwrite/appwrite/discussions/4997#discussioncomment-4670681

I have used vercel for frontend hosting and appwrite and digitalocean for backend how to connect to domain

You'll have to look into the docs for your domain provider for how to configure your domain.

Is this 1st, main domain you're configuring for your Appwrite server?

Yes

How should I configure vercel appwrite and digitalocean

so you typically need an A record that will point your domain to the IP address of your server

This might help: https://www.godaddy.com/help/add-an-a-record-19238

Out of these three where should I add this A record

what do you mean?

I mean where should I add custom domain vercel,appwrite or digitalocean
