Subdirectory issue

Hi!
I have two different WordPress installations :

1- mydomain.cm
2- mydomain.cm/en

mydomain.com is verified and working without any problem with cloudflare.

But there is a problem with mydomain.com/en

Cloudflare doesn’t working on subdirectory

What I have to do?

Thank you very much.

For the same domain name, it has nothing to do with the directory. After the website is started, the whole website will use CDN.
