We will need debug logs to be able to tell what this is. I've never seen a 451, but it may be some restriction in China. https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/451

Thank you for the response, will try to get the debug log for detail support btw Teslamate is working not sure this information is useful

hi alandtse here is the debug log, seems the problem is residing in permission in accessing the website "https://owner-api.teslamotors.com/api/1/products" is there any work around or address update that needed to be made

If you're based in CN, you have to use the right domain. Are you using auth.tesla.cn when setting up the integration?

[rpeng6]
