Non-standard port w/ tunnel: "Your connection isn't private"

Setting up a non-standard port with argo tunnel. Followed instructions here: and set the DNS to a gray colored record. The server I am forwarding to is home assistant server, and I’ve set up the certificates (origin.pem and privkey.pem) from the cloudflare dashboard / SSL tab.

So, all that being said, I get Your connection isn’t private on my browser, showing further:

Subject: CloudFlare Origin Certificate

Issuer: CloudFlare, Inc

Any ideas? Thanks!

This is why you see the certificate error.


Thanks for the answer!, though it’s confusing because:

  1. the docs said to do it that way
  2. if I don’t do it the gray-way, then nothing happens at all on the non-standard port.

Other thoughts?
