@rikukale did this stop working when you upgraded to Virtualmin 7.50.0 ?
Yep, I’m 99% it did.
Looks like I have hit this exact same issue, I have also set apache_star=2 and can see * instead of IP address when creating a new sub server now.

Thanks
Could you please try the latest development version of Virtualmin to see if the issue still exists? We have completely removed apache_star option.
You can install the latest development version by running the following command:
curl -u YOURSERIAL:YOURKEY https://software.virtualmin.dev/webmin-virtual-server-latest.deb -o webmin-virtual-server-latest.deb && sudo apt-get install ./webmin-virtual-server-latest.deb && rm -f webmin-virtual-server-latest.deb
still an issue w. 7.50.0 GPL - see my “bug report” here
