NEWB_My connection to Lenovo Tiny keeps dropping

Hi guys and gals

My first post here.

My local connection to my HA server keeps dropping. The only way that I can access it, again, is by rebooting HAOS on the Lenovo Tiny. Same with the remote access on my phone.

I have a fixed IP address, but can’t access the ISP router to reserve the address. What gives?

Edit 3 - can’t fix IPv6 address - wants a gateway, (which i assume will not be the same as IPv4)

I do get a Thread failed to start error on reboot, if that’s relevant.

I found these errors, too

How do you reboot HA OS?

Hard reboot on the PC, (power button)
