Changing origin server port to 443 in CloudFlare

Hello,

Can someone tell me how to change the origin server port to 443 in CloudFlare?

Thank you very much for your help.

What are you trying to do?

In case you have an application running that is not listening on ports proxied by Cloudflare, you could use Workers, or install a reverse proxy in your orogin.

The following ports are proxied by Cloudflare:

Instead if you have a website running on HTTPS, with a valid certificate, so that it requires port 443 then simply switch the SSL mode to Full (Strict) in the Crypto tab.

Note that on port 443, probably excluding the use of Workers, you can only run HTTPS.
