Website on custom port

Help
1

I am trying to find out, if I can use let’s encrypt in my setup:

We are running a production-server and several test-servers behind a single IP.
For this, port 80 is routed to a webserver that responds with the appropriate redirect:
For production: https://application.mydomain.com
For testing: https://applicationtest_x.mydomain.com:2044x

We then use the port to route the request to the appropriate webserver.

Since I thought that the CA follows redirects, I expected it to work. But during authorization, certification for the custom ports is rejected.

Is this an error on my side or is this the expected result for this case?

This is the expected result. LE will follow redirects, but only to (1) a different host, or (2) HTTPS. They won't follow redirects to other random ports.

And, for as far as I know, (3) different paths (i.e., from /.well-known/acme-challenge/ to /foo/bar/). Not sure about the filename though.

The answer might even be “everything but the port” :grin:

Everything but the port and also (4) not raw IP addresses. :stuck_out_tongue:
