Frage: MacOS calendar app TLS error
during background calendar synchronization I was recognizing TLS errors in the last time.
The TLS error message says, that the TLS certificate isn't valid. In the Org Part of the certificate is Ubiquiti Networks mentioned and as OrgUnit devint. Last implies, that this certificate should be used internal for development.
Just to clarify: I'm not using Ubiquiti Networks Inc. devices at my home network. Only Apple and german vendor AVM.
Is apple using Ubiquity Networks devices and is there something wrong in the deployment of virtual network configurations?
