Unable to access domain from internal network when using Cloudflare's Orange Cloud

What is the name of the domain?

What is the issue you’re encountering

When Orange Cloud is activated, access to the internal network through the domain is not possible.

What steps have you taken to resolve the issue?

I also tried using Zero Trust instead of Orange Cloud. While it is possible to connect to the external network, it is impossible to connect to the internal network through any method through the domain.
No problems occur when disabling Orange Cloud.

What issue are you getting exactly ?
