unable to change my TinyPilot voyager2 use at static IP

Hi There
I have followed your guide regarding change my unit from the default DHCP til static IP: https://tinypilotkvm.com/faq/static-ip

But i keen getting an error every time.

Here i my first try:

pilot@tinypilot:~ $ export TINYPILOT_STATIC_IP="10.100.7.12/22"
pilot@tinypilot:~ $ export ROUTERS="10.100.4.1"
pilot@tinypilot:~ $ export DNS="${ROUTERS} 10.100.8.10 8.8.8.8"
pilot@tinypilot:~ $ curl --fail --silent --show-error \

https://tinypilot.local/scripts/set-static-ip.sh | /bin/bash &&
sudo reboot
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

So now i tryed to supress the certificate error, and got this error:

pilot@tinypilot:~ $ export TINYPILOT_STATIC_IP="10.100.7.12/22"
pilot@tinypilot:~ $ export ROUTERS="10.100.4.1"
pilot@tinypilot:~ $ export DNS="${ROUTERS} 10.100.8.10 8.8.8.8"
pilot@tinypilot:~ $ curl --fail --silent --show-error --insecure \

https://tinypilot.local/scripts/set-static-ip.sh | /bin/bash &&
sudo reboot
curl: (22) The requested URL returned error: 404

I just need to set the unit to use at static IP instead of the DHCP....why is this such a problem

Note: I have used the "https://tinypilot.local/scripts/set-static-ip.sh | /bin/bash && " instead of the "https://tinypilotkvm.com/scripts/set-static-ip.sh | /bin/bash && " in the guide..because i dont know where "https://tinypilotkvm.com" is. I access my TinyPilot from "https://tinypilot.local"

Can anyone please help me, so this unit can be of some kind of use. I have spend a lot of time troubleshooting with no solution in sight.
