401 Error when Getting Users

When I do a GET request to: https://api.zoom.us/v2/users/ I keeping a 401 error with the response:
{“code”:124,“message”:“Invalid access token.”}. I am not using any query parameters.

I am pretty certain this didn’t use to happen. I am using OAuth 2 for authentication. I know the issue isn’t with the access token because when I use the same access token to for example get a users meetings with: https://api.zoom.us/v2/users/me/meetings I get a 200 Success. The issue is JUST happening when getting users. I have an app that serves over 1000 users and all my users using this particular endpoint have been having issues.

What I am doing wrong or what has changed recently?

Thanks,
