Change subdomain in cloudflare access

I recently changed the subdomain name from

https://subdomain-old.cloudflareaccess.com

for

https://subdomain-new.cloudflareaccess.com

for example

and now the route

https://subdomain-new.cloudflareaccess.com/warp

It does not load me from linux to connect to warp in my organization and I have tried to wait a few hours thinking that it is a programming issue or changing my network. but still nothing.

could someone help me please.
