iOS 绑定deviceToken出错： Update push configuration failed

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    [JPUSHService registerDeviceToken:deviceToken];
    [[EMClient sharedClient] registerForRemoteNotificationsWithDeviceToken:deviceToken completion:^(EMError *aError) {
        if (aError) {
            NSLog(@"环信：绑定deviceToken错误  %@",aError.errorDescription);
        }
    }];
}

收到deviceToken后，调起SDK绑定，然后就返回错误：Update push configuration failed，线上版本和开发版本都出错，检查了证书没啥问题，不知道怎么回事，求助~
