I have followed the instructions from the following link:
As shown in the images, I have configured the DNS record, enabled the proxy in Cloudflare, and set the SSL mode to Full, so I don’t understand why I am still getting “Invalid Configuration.” I have checked other related topics, but they haven’t helped me resolve the issue.
The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.
You can also use v0 to narrow down the possibilities.
Thank you for reaching out to Vercel Support! We are happy to help out with your domain.
It is possible use Cloudflare as a proxy in front of Vercel by setting the SSl encryption mode to Full on Cloudflare. For more on this setup we do have a guide and troubleshooting steps here: Vercel and Cloudflare Integration
If you are also using Cloudflare Access as the protection layer for the site. It will redirect all requests to Access. In such case, you need configured a bypass rule in Access that will allow the requests to the /.well-known/acme-challenge/* to pass through.
Okay, so I need to access Access in Cloudflare, then to Zero Trust, and there in which section do I define the rule that allows traffic through /.well-known/acme-challenge/*? Thank you so much sir
