Sophos Mobile DEP and VPP. Can't install apps anymore

Hy! 

Sophos Central Mobile

We configured DEP and VPP. All works well and we can install apps on the DEP Iphone.

But now I can't install apps anymore.

We got the Message. Commands sended and then Abort and it doesn't install the app.

I can't find any logs and so.

Does anyone know why this happend?

Iphone 11 IOS 14.2

Failure Code -45

InstallApplication Error [12064][MCMDMErrorDomain]Could not retrieve license for the app with iTunes Store ID 546505307. [2605][DeviceManagement.error]null
