**Description**

Hey @tuancode,

Please see the work around here:

> [@500 Internal Server Error during App Authorisation](https://devforum.zoom.us/t/500-internal-server-error-during-app-authorisation/15962/4):
>
> Hey @okzoomer, @gohsyang, We are aware of this issue, it will be fixed this weekend. Current work around is to login first here: [zoom.us/signin](http://zoom.us/signin) and then go back to authorize the app. Apologies for the inconvenience, Tommy

Thanks,  
Tommy
