Domain ok but subdomain not ok

Website, Application, Performance DNS & Network

Hi all,
I registered my domain yesterday, so I changed the DNS on my hosting.
My domain is accessible: https://domaine.com but the subdomain is not accessible: https://sous.domaine.com.

Do you know why ?

THANKS

Your domain does not use Cloudflare. Check with your host.

Hello, sous.domaine.com was a example.
My website is ok on cloudflare, (see https://cf.sjr.org.uk/tools/check?6a1321ddc07b4d5f81ac1ffdf4ae08c9 )I start to be able to access on certain page but it’s very very slow.
Why ?

The initial connection to the Cloudflare proxy is fast, then there is a 5-6 second delay before the response comes for the (uncached) page. The rest of the linked files then download quite quickly. Seems to be a slow response from your origin.

Try setting the DNS record to “DNS only” to bypass Cloudflare and see if the problem is still there and check your origin server. Maybe there is a slow database lookup or something.
