- You must make sure your AppId and Secret Key SDK Qiscus are correct.
- Make sure that the JWT made by your server is valid, to check valid or not JWT can check on jwt.io (http://jwt.io/).
- The last step, you have to make sure the server to make JWT must have a valid GMT time. To make sure, please do Synchronize Time from the Network (NTP) on your server. If your server is Linux OS, you can use timeset to synchronize your time network. Run it from your terminal.
