I’m getting an error message whenever I want to run Software Update to upgrade to the latest software versions:
“Could not connect to the server. An error occured while installing the selected updates”
The logs in the console show the following failures:

According to Apple’s documentation, the error means the application could not connect to the host ->NSURLErrorCannotConnectToHost = -1004,
If I connect through a mobile hotspot (Sunrise), the download works, so it must be related to my network connection. Of course tried resetting that etc, to no avail. Could it be that my UPC has misconfigured their network and stops SoftwareUpdate from making the necessary connections?
