Can't access HA from browser or app

Installation
1

Hello,
I need help, I can’t access HA from browser on the network or from remote access app sonce yesterday. I have no idea why it happened, i recently added an access point, and the music assistant app, but it worked fine afterwards for a short while.
I have an old pc on which I installed the HAOS, and it’s connected directly to internet via LAN.
The computer starts up, and show no obvious problem. I have access to what I assume called SSH (?) on that HA computer, and automations keep running.

How can I regain access to it? Any ideas?

Thanks.

What happens if you try http://10.0.0.220:8123 ?

Nothing, tried it several times, it does not load the page “ERR_ADDRESS_UNREACHABLE”

I also tried turning off the computer several times, none of it helped

So from the PC you are trying to reach the HA install:

  • Is it in the same subnet? Does your PC have an 10.0.0.X address?
  • Can u ping 10.0.0.220 from that PC?

Thanks for the help efforts!
I managed to solve it by resetting the router, now everything is back to normal, don’t know how or what happened but it’s working again.
