today one of my user get nil when call [[MobileRTC sharedRTC] getMeetingService] .  
His device is ipad and ios version is 9.0. SDK version is: [v4.1.34076.1024]

According to previous topics

> [@getMeetingService returns null](https://devforum.zoom.us/t/getmeetingservice-returns-null/681):
>
> getMeetingService is returning null in the below code: - (void)startMeeting:(BOOL)appShare { MobileRTCMeetingService \*ms = [[MobileRTC sharedRTC] getMeetingService]; if (ms) { NSLog(@"ms Exists"); If I remove the if-statement I get a success code, but the meeting still doesn’t start: NSLog(@"onMeetNow ret:%d", ret); // Logs "onMeetNow ret: 0" &nbsp; Here is my View Controller code: [https://gist.github.com/tyleralves/ce0ed47d46655b68e9539a4324bfe76d](https://gist.github.com/tyleralves/ce0ed47d46655b68e9539a4324bfe76d)

> [@MobileRTC Service nil](https://devforum.zoom.us/t/mobilertc-service-nil/1572):

> I am using zoom sdk in my ios 11.4.1. It was working fine when I released the app. But now after few days, its not working any more. I am getting nil on executing this - MobileRTC.shared().getMeetingService(). It has already been authorized in appDelegate successfully. But still getting service nil in my main view controller. Please help ASAP. &nbsp;

I check my code, I am sure my app first do auth successfully and then call getMeetingService. Among of thousand users only one user get this error.  
so my question is: is there other reason leading to this error?

Hi Guan\_bj,

Thanks for using Zoom SDK. Is there anyway you can get the error log from the user? Is the `getMeetingService` always get `nil` or just get `nil` occasionally? Could you provide more info on how can we reproduce this issue?

Thanks!

getMeetingService return nil, it means SDK Auth was failed. Please make sure that your app checked the result of SDK auth callback at first. We also provided an interface: “- (BOOL)isRTCAuthorized”, and you can call this interface before you try to start/join meeting.

BTW, please check the returnValue of SDK Auth Callback before you are going to start/join meeting with SDK:

- (void)onMobileRTCAuthReturn:(MobileRTCAuthError)returnValue

Thanks,

Robust

Hi Robust  
Thanks your reply. I am sure I do join action in

- (void)onMobileRTCAuthReturn:(MobileRTCAuthError)returnValue  
successful callback status.  
I can try isRTCAuthorized before starting.

For Carson, I can’t provide any more info because all API call is successful and only one user get this error.
