  How do you know that the configuration is working?

  We don't need to see errors from systemd.  They're not relevant.  We need to see the debug output.

  1812 is the port used by FreeRADIUS.  So you have one of a few situations here:

1) there's already a copy of FreeRADIUS running

2) you've broken the configuration, and told the server to listen on port 1812... twice.  So it opens the first port, and that's OK.  But it then tries to open the second port, and sees that it's already in use.

  How did you create the second virtual server?  Did you copy the "default" one?

  The more information you give us, the easier it is for us to help you.  If your message is just "I did stuff and it doesn't work", then there's little we can do to help.

  As with any IT admin process, you need to have a systematic approach to tracking down the problem and solving it.
