I needed to update my router and the new router uses different a different IP address range.
Ever since I changed I can no longer access homeassistant remotely.
The original installation “just worked” so I have no ideas what might be happening. My homeassistant has been updated/rebooted and has the proper new IP address and is accessible on my local network. When I turn off wifi on my phone and connect the tailscale app it shows connections for both my phone and the homeassistant.
