Hi,

Unfortunately, we have a problem installing an app on a few devices.

An error message AMSErrorDomain 203 appears.

Unfortunately, we can't do anything with this message. It is also strange that it only affects some devices:

"AMSErrorDomain erreur 203. / The operation could not be completed.
(AMSErrorDomain error 203) I No server with the specified host name was detected.
detected. The operation could not be completed. (kCFErrorDcmainCFNetwork erreur -1003.)"

What does that mean? Where can we find the problem?

Regards and thank you very much in advance.

Hi,

It seems that JAMF Safe Internet RADAR was blocking Apple App Store.
Unfortunatly its not clearly descript/marked in the JAMF Safe internet dashboard what is blocked by the internet filter.
