Error 516 in SMP 2.3 - iOS

[Former Member]

Hi,

I am getting Error code 516 while synchronizing data in iOS app from SMP 2.3. The device gets registered and then the app does not move forward to home screen. The log file shows following error in Xcode :

SUPConnectionStatus_DISCONNECTED, code = 516, message = Error: 516 Detail: Error sending request to server Native                Error: -2 Source: moClient.cpp 1907.

Another app with the same configuration works but when I am trying to replicate the same configurations with new app, it throws the above error. Please help.

Hi,

Thank you all for your inputs. The error was because of the wrong name of the sync group.

After I have modified the sync group name, I am getting another error :

Terminating app due to uncaught exception 'SUPPersistenceException', reason: 'Sync failed: -857 (ERROR) %1:[-10244] The MobiLink server has encountered an error and the s;Parameter 1:[-10244] The MobiLink server has encountered an error and the synchro'

Will Appreciate your help.

Thanks

Make sure you are passing SK and PK in any from device. Keep an external breakpoint (debugger) in RFC (logged in as same user used from device) and check whether RFC is triggering, if yes see check the input values coming from device.

Make sure you are able to do a preview of the MBO from sybase workspace too.

sync failed -857 error generally comes when your request is not reaching from SMP to backend system.

Have you verified the sync profile settings in current app with the working app?

If settings are correct, please follow the steps what Midhun has asked you to.

I doubt if something wrong with your synchronization profile.

Please cross check with sync profile for working application. In general, sync profile should be:

server: Relayserver

port: 443/80

stream parameter: url suffix(/ias_relay_server/client/rs_client.dll/RBS farm id)

Note: Assuming Relay server is running in window server.

Is there a reverse proxy, Relay Server, and/or firewall in the landscape?  Is the device connecting over cellular network or wifi?

Thanks,

Andrew.

@Andrew There is a relay server and the device is connecting over cellular network. This problem occurs with a new application with same configuration settings while another one runs fine.

Thanks

[Jitendra_Kansal]

what do you mean by same configuration settings? Can you please share the iOS code for synchronization?

Rgrds,

@jitendra Same configuration settings mean the serverName, portNumber, FarmId etc. I can not share the code right now but the logs displays the error right after the device gets registered on SCC.

Thanks
