The 'exp' value exceeds the maximum value of 60 seconds beyond the issue time

Trying to generate the access token using the API https://api.box.com/oauth2/token with grant_type as "urn:ietf:params:oauth:grant-type:jwt-bearer" and getting the below error:

{
    "error": "invalid_grant",
    "error_description": "Please check the 'exp' claim. The 'exp' value exceeds the maximum value of 60 seconds beyond the issue time."
}

Please Help!
