Https always redirects to IDRAC server interface


Any help would be much appreciated!

My domain is:

I ran this command: $ sudo letsencrypt --apache -d -d

It produced this output:

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you’re confident your site works on HTTPS. You can undo this
change by editing your web server’s configuration.

Alternate names not found in the certificate

What does this mean?

We were able to retrieve a certificate for this site, but the domain names listed in it do not match the domain name you requested us to inspect. It’s possible that:

  • The web site does not use SSL, but shares an IP address with some other site that does.
  • The web site no longer exists, yet the domain name still points to the old IP address, where some other site is now hosted.
  • The web site uses a content delivery network (CDN) that does not support SSL.
  • The domain name is an alias for a web site whose main name is different, but the alias was not included in the certificate by mistake.

I chose to ignore the mismatch and, the results were…

You might have an existing self-signed certificate in a _default_ VirtualHost in /etc/apache2. If so, you should get rid of the default HTTPS VirtualHost that uses that certificate.


Thanks for the reply!
In my /etc/apache2/sites-available :
I have a 000-default.conf that contains each of my vhosts, but all created by me and none are IDRAC or localhost or anything like that.
I also now have a 000-default-le-ssl.conf which contains the info for and only.


I have since renamed 000-default.conf and 000-default-le-ssl.conf to my own names, disabled the old, and reloaded apache2 service. Same results.


It seems like your Internet routing is not forwarding the HTTPS traffic to the IP of your server.
But instead forwarding it to the IP of the DRAC.


I agree, it seems unlikely to me that it’s possible for Apache misconfiguration to cause this.

iDRAC is on a different physical network port, right?


Well, your suspicions were correct. Turns out my partner had the internal routing redirecting https traffic to IDRAC and I didn’t know about it. Thank you all for your help!
