HA behind Cloudflare ZTNA, app won't connect

Mobile Apps Home Assistant Companion for Apple
1

It used to work, not sure why its not working anymore.
I have HA behind CloudFlare ZTNA. When I use web browser (Mobile/Desktop) I can access without any issue.
When I use the mobile app, I see the HA login screen, enter my correct credentials, and then this error:

"Faile to Connect
X
The data couldn’t be read because it isn’t in the correct format.
Error Code:
NSCocoaErrorDomain 3840

I should also mention I have Trafik in front.
Nothing intersting in HA logs:

Hi, Not much of help… But I can confirm that exactly same issuecan be seen when I use Azure Application proxy to publish HA.
I get same error messages. It works using browser. The app is not working on my MacOS client but works fine when using the app on my Samsung smartphone.
