524 CDN Error

Hello,
I have a small problem on my site, I have an error 524.
It’s a WordPress site on which I installed Litespeed Cache, I connected and configured to Quic.cloud.
I was connected to the CDN of Quic.cloud with modification of the CNAME.
Except that finally I did not want to use the CDN, so I made the following changes:
– Rename of the CNAME
– Deactivation of the CDN in the interface on the quic.cloud site
– Delete the domain to connect it to another account: https://quic.cloud/docs/billing/how-do-i-move-a-domain-from-one-user-account-to-another/
Except that I can’t access to the site with the error 524, what can I do?

The page I need help with: [log in to see the link]
