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?
