React App not working with S3 and cloudfront anymore

Question

I have been deploying my react frontend applications with S3 and cloudfront for a long time now. I had one deployed for a few months which just recently stopped working. I checked the s3 static website hosting url, http://domainname.s3-website.ap-south-1.amazonaws.com

Here my app was working perfectly fine but when I check the actual domain or the cloudfront url, https://cfdomain.cloudfront.net/ , it doesnt work and rather shows just a completely blank screen with no logs in the console.

Unfortunately, I cannot share more details as they are confidential.

Please suggest what I should do to fix this and it get back to how it was before when it was working.

Any help is appreciated

Thanks
