Problem Joining Work Profile From Android Device

yes, my token expiry is about 24hrs...

here is the token create payload function:

private static String getQrCodeStringWorkProfile(String enterpriseName, String policyName) throws GeneralSecurityException, IOException {
EnrollmentToken token =
new EnrollmentToken().setPolicyName(policyName).setDuration("86400s").setAllowPersonalUsage("PERSONAL_USAGE_ALLOWED");

return getAndroidManagementClient()
.enterprises()
.enrollmentTokens()
.create(enterpriseName, token)
.execute().getQrCode();
}
