TeslaApi.Error 403 on v4.0.0

[gurpreetz]

Is there an existing issue for this?

• I have checked the existing issues and discussions, and I can confirm that there are no duplicates.

What happened?

I noticed teslamate was throwing errors, and upgraded to v4.0.0
I'm running on a raspberry pi 5 - so the host is compativle with this version.

I now consistently see:

Same here, working fine on update earlier this morning but errors just started up again a few minutes ago.

[tuxeri]

Same problem here, update to 4.0.0 did not solve it.

[Olrik-WP]

Same problem here, update to 4.0.0 did not solve it.

[actstorms]

Same problem

[scottismyname]

It was working 10-15 minutes ago (on 4.1 dev) and just broke again

[Seji64]

Same Problem. env: Docker (x86 on a Synology). Can provide Logs etc if needed.

[dcw88]

I have the same problem

[Nicnl]

So.... what is happening exactly? Tesla is killing the owners-api and forcing users to use the (PAID) fleet-api?
That would be a bummer, because I only have my own personal Tesla.
So paying to gather the stats of a "fleet" of one vehicle is kinda bullshit.

[scottismyname]

Nobody knows at this point

[actstorms]

The integration for homeassistant works and it looks like it using the same api endpoints. So i think the problem is in teslamate.

which homeassistant integration are you using?

[Olrik-WP]

Are you using fleet api not the owner api ?

[dcw88]

Does Teslamate support tesla fleet api?
