Apple Software Update not working over UPC connection


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?

Re: Apple Software Update not working over UPC connection

@G-News , Please try to restart your modem once. Does it work afterwards? Basically we do not block WWW addresses. Do you operate your modem in bridge mode?

Re: Apple Software Update not working over UPC connection

https://forums.developer.apple.com/thread/16231 this probably covers the problem best. It's a caching issue that arguably has nothing to do with the internet connection but with the network I'm in.

Re: Apple Software Update not working over UPC connection

@G-News , Have you changed the DNS server on your computer or are you using the one from UPC? I am not aware of any such errors and I can get the updates from home without any errors.

Re: Apple Software Update not working over UPC connection

Thank you. I have tried both the stock DNS the connect box provides as well as custom entries directly in os x. That didn’t help.

I did find that os x must have got a hickup with its Asset Caching however. Flushing the caches and deactivating the function in AssetCacheManagementUtil manually (although I never consciously turned that feature on) finally let me download the updates. Will see at home tonight if they’ll also install. Pretty sure now this has nothing to do with UPC internet and a lot with Apple having bugs in their AssetCaching feature that were introduced in High Sierra.
