Oath Success and Failure Url, is going to a blank page

I have a domain with QSERERS

Which --> designgrid.com.ng

I forward ⏩ the A Record to Vercel where am hosting my Frontend.

Vercel generated an SSL for the domain

In Vercel, I created a CNAME appwrite and VALUE cloud.appwrite.io

I added my domain to Appwrite and successfully verified.

Now my custom endpoint looks like appwrite.designgrid.com.ng

I replaced https://cloud.appwrite.io/v1 With https://appwrite.designgrid.com.ng

In my code

Which now looks like

`client.setEndPoint("https://appwrite.designgrid.com.ng").setProject([My Project ID]);

The question is

When I use the custom domain as the success and failure urls to redirect to

https://appwrite.designgrid.com.ng/dashboard

It shows a blank page for a while then redirect automatically to Appwrite website.

In fact I only want to redirect to my actual domain which is https://designgrid.com.ng/dashboard

TL;DR

The user is experiencing an issue with the Oath Success and Failure URLs redirecting to a blank page. The solution is to ensure that the client endpoint includes "/v1" and that the platform hostname matches the domain being used. They also need to register their front-end app as a platform in the Appwrite console. When setting the success and failure URLs, they should use their own domain, not the Appwrite domain. The user has a domain with QSERERS and has forwarded the A Record to Vercel where their frontend is hosted. They have also created a CNAME record in Vercel for "appwrite" with
