No connection HA via zerotier

DeGrootste · December 25, 2025, 9:26am

Hi all,
Both devices, android phone and HA are authorised in zerotier and seen/connected in the webapp. But no connection when wifi is disabled on the phone. Addon is running and all is started in logfile. I don’t know where to search.
Does anybody has an idea? Search in topics dudn’t give any solutions. Thanks anyway.
Greets, Sander.

What browser are you using and on what Android device? Have you the latest updates on that device?

If your WiFi is disabled on your phone, does it use an alternate form of connection to zerotier? What? Mobile, BlueTooth, Infrared, optical, sonic? How have you configured that?

Hi, thanks for your reply
I use Chrome v.143.0.7499.146
Android 11, last update 2022
Mobile connection.
Both client (phone) and addon (HA) configured as private on zerotier. Authorised and both have connection with zerotier.

Any blocker addons on your phone browser? Is javascript disabled?
What panel are you trying to display?

DeGrootste · December 25, 2025, 11:14pm

No addblockers, JavaScript is enabled. I’m trying to display normal landingpage

You’ve cleared the browser cache?

Have you tried a different flavor of browser?

DeGrootste · December 25, 2025, 11:21pm

No, not jet. Will try that Tomorrow. So thanks and good night

Try uninstalling and reloading your Companion app too.

Hi, I tried all that, no luck.
Even did deleted network on zerotier and made a new one with new ID. Both devices authorised in zerotier.
Now I see this in HA Core logging. Authorisation to HA is invalid in some kind of manner. Connection is there, but no passing through
