Cable modem has failed. Homeassistant not functioning

What have I got wrong?

My cable modem has failed and will not be repaired until tomorrow afternoon.

My network (router and wifi) are still functional.

However, my home assistant is not functioning. No lights. No security system. No flood prevention. No home automation. I can’t access home assistant from the iOS mobile app nor from my laptop.

Please advise.

Thx.

What url are you using to access your HA?

I figured it out. The mobile app was trying to connect via the cloud.

Thx for your help.
