Mobile application monitoring traffic via Cloudflare

Has anyone implemented iOS or Android mobile app monitoring successfully in Managed, where Cloudflare is used along the application delivery chain?

We've configured a Cluster ActiveGate, Cloudflare and the relevant firewall rules but when we run the endpoint test via CMC, all tests fail. Traffic flow would be: device -> Cloudflare -> F5 -> Cluster AG.

If we change the setup to bypass Cloudflare, the connection tests succeeds, leading us to believe the issue lies with Cloudflare, but we don't know what or why. Any suggestions would be welcome.

Also, I assume the test is run from Mission Control? Is there any specific traffic that has to be allowed which is sent back to MC or once successfully deployed, to the mobile device?

Did you checked steps from this article? https://www.dynatrace.com/support/help/deploy-dyna...

Are you sure that port is opened?

I have yes, port 9999 is open on Cluster AG, but it seems like it gets dropped on the Cloudflare level so I was hoping someone in the community have set it up like this before.

Cloudflare only allows certain ports, as per their documentation, but logically it should still work if set up like this: user -> 443 -> Cloudflare (443 is acceptable port) -> 443 -> F5 -> 9999 -> Cluster AG

Is there any logging which will show the requests hitting the AG? We suspect the request gets to the AG, but Cloudflare adds headers which confuses AG and therefore the tests fail.
