Thank you for your answer. I gave up on it at the time. I did work for days and I think it is the problem it works over TCP. The Web (Browser) could reach it and all worked, but the APP could not reach it. So I guess it is cloudflare blocking TCP. Am happy for all answers, so I can check on it later on again. Thank you.





I have it on a raspberry pi in a home network. Connected with a reverse cloudflared and in cloudflare in did set up the domain over the Tunnel routing on the right port. I think the problem is cloudflare only allow http and the data bis send over TCP. Thank you for your nanswer. When I bhave more time I will look again into it.
