Help with the error.log

Can someone tell me what this error.log means and were I have to look?

Thanks for helping.

It’s probably not getting back the data. There are a number of reasons this could happen, but the most likely is probably that’s it’s not properly authenticated.

If you created a new account for it, have you gone into the device activity to approve the login? Otherwise, have you tried deleting the cookie file Home Assistant creates and restarting?

Hi tboyce1, you start with “it’s probably …” But what is “it”?
I cleaned the cache/cookies but it still gives the error.

Because I have no clue where to look I am completely in the dark.

Sorry, I meant the cookie file that Home Assistant creates and stores to save the authentication. I don’t use the component currently, but the docs say

This platform will create a file named .google_maps_location_sharing.cookies extended with the slugified username where it caches your login session.

Probably somewhere in your config folder (maybe under .storage?). You can try deleting that and then restarting Home Assistant. It should try to authenticate again and create a fresh file. If the file is recreated and it still fails, then the authentication itself may be failing, possibly due to Google blocking the login for one reason or another.

Thank you very much. I will try asap.
Found the file and renamed it. Now restarting.
