Static IP Address not working with Starlink

Hope someone is able to help here…

I changed the IP4 Address in Home Assistant to a static address due to Starlink not being able to sort this.

Rebooted everything including my mesh network and although the RaspberryPi shows up in the Devices list of Starlink app, it gets the new IP address briefly then goes blank repeatedly?
So now I cant login to HA at all.
Mucked around most of last night and this morning but still have the problem.
Anyone have any ideas here?

I do not know Starlink, but it sounds like you are directly connected to the providers network with your HA server and then you might not be able to just choose a static IP.

How are home assitant and the starlink connected?

Are you using a 3rd party router?

Dude, put your own router between your stuff and that Starlink router…
Satellites pass by very quickly.

It connected to the starlink router ethernet port directly

I was hoping not to have another device
