Edge Certificate DELETED even tried API endpoint

My website ikute.vn can using with ssl from let’s encrypt but I want to using proxy from Cloudflare. I have check Universal Edge Certificates got deleted.
I have tried Disable Universal SSL and Enable Universal SSL several times but it not working.
I also tried API endpoint here, it showing “success”: true but not working too

i posted this same problem 3 days ago, haven’t gotten a response and the free universal edge cert is still in deleted status.

the curl fix completed successfully, like it did for you, but it didn’t fix the issue.
