If you can't access your server and your router's web interface, that's a subnetting/DHCP allocation issue. Nothing to do with Pi-Hole.
For reference, there's 2 ways to allocate static addresses to devices:
- Define DHCP range, and configure the application to use a static address outside of the allocation pool.
- Give out static addresses by MAC.

I love these guys. Let's see if somebody can just bootstrap the FOSS framework directly on TCP to work on the internet without a VPN. Fantastic project
