Not able to launch Zoom Meeting

I am using Zoom SDK, Version - 5.16.10 and i am not able to launch the zoom meeting i am not getting success after passing the JWT token.

As the token which i am getting i am verifying it on https://jwt.io/ website also but it is giving Invalid Signature but after doing changes on my JWT token got verified also then i pass that token in my SDK also but still i am getting 

"tokenWrong" error. As i have tried multiple times but not got success also my client key and secret key is also correct as i have verified it also. So problem is that after passing correct token also i am not getting success . Please help me!!!
