**I created the signature using jwt.io using the following** Header: "alg": "HS256", "typ": "JWT" } Payload: { "appKey": "", "sdkKey": "", "mn": "", "role": 0, "iat": 1667592404, "exp": 1667592404, "tokenExp": 1667678446 } (and using my SDK secret which I won't post here, I checked and I am using the correct SDK secret and I am not checking "base 64 encoded")

your “exp” is wrong, should be

  const iat = Math.round((new Date().getTime() - 30000) / 1000)
  const exp = iat + 60 * 60 * 2
   ...
    tokenExp: iat + 60 * 60 * 2
  }

The comment above is correct - I was incorrectly sending the same iat and exp, when it is tokenExp and exp that should be the same, NOT iat and exp.
So this would be a corrected one then (when sent at the right time - by the time you are reading this the timestamps are too old):
{ “appKey”: “YOUR SDK KEY”, “sdkKey”: “YOUR SDK KEY”, “mn”: “ZOOM MEETING ID”, “role”: 0, “iat”: 1667592404, “exp”: 1667678446 , “tokenExp”: 1667678446 }
