[Bug]: refresh token not working, keep throwing 403 error
### Describe the bug

Problem: plugin keeps complaining 403 error while startup.

I followed wiki to generate new refresh token (through UI and command line), but the plugin still won't be able to authenticate. The generated refresh token seems correct, because copying it to Nest plugin config and it can work flawlessly without problem.

Not sure why nest-cam can't login. The debug log doesn't contain useful information, see below.
