Question about Cloudflare Tunnel and HTTPS Traffic Without a Certificate

What is the name of the domain?

kasm.idrone3d.com

What is the error number?

Not applicable, as there is no specific error code.

What is the error message?

The service I am trying to expose requires a secure connection (HTTPS) but does not have a valid certificate, which prevents the connection through Cloudflare Tunnel.

What is the issue you’re encountering

I have set up a Cloudflare Tunnel to expose a service running on my local network. This service listens on a port equivalent to 443 and requires an HTTPS connection, but it does not have a valid SSL certificate. When I try to access it, the service rejects the connection due to the missing valid certificate. I need to know how I can configure Cloudflare to handle this traffic without requiring a certificate on the origin service.

What steps have you taken to resolve the issue?

I configured Cloudflare Tunnel with the subdomain kasm.skystudyzone.com, pointing to the service on my local network.
I tried different configurations in Cloudflare Zero Trust, but it still requires a valid certificate on the origin.
I attempted to access the service directly via IP and port, and it works correctly without Cloudflare.
(If you have a screenshot of the error message, upload it in the corresponding section).

What are the steps to reproduce the issue?

Set up a Cloudflare Tunnel pointing to a local HTTPS service without a valid certificate.
Try accessing it through kasm.skystudyzone.com.
The service rejects the connection due to the missing valid certificate.

The tunnel has a ** No TLS Verify** option.

Try to also set ** HTTP Host Header** and ** Origin Server Name** for the tunnel.
