Undefined Communication Error

Question

Hello Everybody, 
 i have just installed the latest version of SMC and configured Settings, Profiles etc. as named in die Administration Guide. 
 Whem i'm trying to active a Device via Mobile Control App (Android and iOS) the app says that there's an undefined communication error - directly after scanning the QR Code or typing the credentials manually. Theres no Error-Code or something. 
 Has anyone an idea what i could have done wrong? 
 
 Thanks a lot

Hi everyone, 
 there was a communcation issue within the Sophos Central EU-Central-1 region which is now resolved. 
 Our development team will continue to monitor the backend to make sure the issue doesn't reoccur.

Hi Matthias 
 Try this 
 
 Log in to the Sophos Mobile Control web console with a super administrator account 
 Go to "Setup | System setup" 
 Switch to the " SSL " tab 
 Press the " Auto-discover certificate(s) " button 
 The Sophos Mobile Control server tries to detect all SSL certificates involved in the connection. The certificates should be listed after pressing the button. If the Sophos Mobile Control server cannot resolve the external URL (for whatever reason), you have to manually upload the certificates, which will presented to the Sophos Mobile Control clients. Certificates which should be uploaded have to be in the .der or .cer format. 
 Save the changes 
 Try the registration of the mobile device again 
 
 Please note: If your certificates change, you have to update them as well using the procedure above. 
 
 Thanks
