SDK Error: 5 internalErrorCode: 124

Meeting SDK Android
2

I have no solution, but your signature looks good (decoded base64)

{"alg":"HS256","typ":"JWT"}
{
  "sdkKey":"[REDACTED]",
  "mn":"5868415858",
  "role":0,
  "iat":1660329547,     -> Friday, 12 August 2022 18:39:07
  "exp":1660336747,     -> Friday, 12 August 2022 20:39:07
  "appKey":"SSu3dBFMX5Qz7xp3SBwcyDkZByQ5uMlz6s874",
  "tokenExp":1660336747 -> Friday, 12 August 2022 20:39:07
}

it’s the correct version for SDK JWT

the error then lies rather with the init of the meeting, do you use the SDK JWT there?
I know the web api and there you can choose between SDK JWT Signature and JWT Signature.

have a look - same error message - there was the “solution” cors header ??? strange
