How to use the non-standard ports compatible with Cloudflare

Those are HTTP ports not HTTPS, Cloudflare doesn’t support any HTTP ports with Access. If any actually work it’s not a feature and generally a colossally bad idea.

  • Does the application behind Access need to use HTTPS? Yes. Cloudflare Access only secures applications that use HTTPS.
  • Can Access enforce rules on a specific, nonstandard, port? No. Cloudflare Access cannot enforce a rule that would contain a port appended to the URL.However, you can use Cloudflare Cloudflare Tunnel to point traffic to nonstandard ports. For example, if Jira is available at port 8443 on your origin, you can proxy traffic to that port via with Cloudflare Tunnel .
