Hi @collinpark,

Thanks for the info. Based on the payload, please try to limit the `exp` and the `tokenExp` to be at most 2 days from the `iat` time. Please have a try. Thanks!

Hi @username234234234,

Thanks for the info. It seems like you are using API key/secret instead of SDK key/secret to generate the JWT token. Please refer to the instruction here: [https://github.com/zoom/zoom-sdk-windows/blob/master/CHANGELOG.md#new-sdk-initialization-method-using-jwt-token](https://github.com/zoom/zoom-sdk-windows/blob/master/CHANGELOG.md#new-sdk-initialization-method-using-jwt-token) and use SDK key/secret to generate the token.

Thanks!

I know this post is about windows sdk  
but I saw this python repo today and it helped me with JWT generation

What fixed it for me is change the gmt to local time zone on the epoch converter
