Logic Pro not able to complete download...Try connecting to Internet??

I had the same problem and this is how I got it going:

1. Disconnect WI-FI and connect via ETHERNET.
2. Remove external AUDIO connections (Scarlet, Duet etc) and choose NONE in Audio Input/Outputs in Logic.
3. Quit Logic Pro X and DO NOT CONTINUE DOWNLOAD.
4. VERY IMPORTANT: Restart Logic Pro X BUT, when the pop up asks you to continue download, CLICK CANCEL. This will cancel all failed downloads. I had several going and I suspect they were messing up the download.
5. Go to Preferences and Re-Download Sounds.
6. To See the progress, quit Logic Pro X but choose, CONTINUE DOWNLOAD.

I have the same problem, 2 different computers, tried different DNS, VPN, different locations. Sometimes it fails immediately, others it downloads a bit and then fails. Once I was able to download 1GB but then it kept failing and can't resume. Sometimes it resumes a bit.

Possibilities:

1. Issue with their CDN or, more probably
2. Library update (I saw an item I hadn't seen before, Keyboard in the new sound packs) - perhaps to go with an unreleased update of Logic.

Today I opened Logic and said there are updates to sound libraries and got this error too while trying to download. So there must be server issue as other downloads work fine

Ive tried all this and it still fails on 2 computers… 1 using internal drive for library the other and external 

I did some tests and I get the same result as others.

My guess is it is CDN related. I don't know if it affects all regions. I'm in North America (Montréal).

Tried different CDN regions and no dice (using a VPN)

Thanks for the feedback.

CDN localization can depend on DNS settings.

Yep, my VPN also uses different DNS settings so it can seem I am connecting from different places. I tried 3-4 major countries.

Thanks! Interesting.

No problem reported on the Apple System Status site.

I'm having the same issue. I tried the steps andyroyale described and still no luck.

It seems to be fixed now. The extra library content (that I suspect is from an upcoming update) isn't visible any more (Keyboards in the new sound packs, for example).

Same thing here. The Library reports as fully installed now.
