Cloudflare Zero Trust on VNC Browser

Hello Everyone,

I want to secure my application, which is a VNC browser. But I got this error after successfully authenticating.

“The origin has unexpectedly closed the connection. Please confirm that the origin is healthy.”

Please need help for this issue.

Thanks.

Hi @cevinogames,

Have you created a Cloudflare tunnel on the server as in our Render a VNC client in browser developer documentation?

It seems like your origin is not responding on the port that Cloudflare is expecting. If you have already deployed a tunnel on that server, I would recommend you take a look at your config.yml and make the necessary changes as shown below.

tunnel: <NAME>
ingress:
- hostname: sub.domain.com
  service: tcp://localhost:5901
- service: http_status:404

Additionally, be sure that in the Access application settings, in Additional settings, set Browser rendering to VNC.
