When my installation is 5.18 Gb / 5.19 Gb (nearly completed), I get a "Check your connection" error.
Looking at the logs, I start seeing the following message:
[Warning] [12/14/2018 5:42:17 PM] Download attempt 1 failed!
System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).
This error repeats itself up to attempt #10 and triggers a "Check your connection" error in the installer, with the log error:
[Error] [12/14/2018 5:46:15 PM] Error downloading '439ef5c2cf70d3ea7166fd74dc3c9e72afd65bd184e90bd42ef924d27b47d642'!
Daybreak.Net.FileDownloader+FileDownloaderException: Retry count exceeded! Giving up. ---> System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).
If I restart the installer, it'll resume and continue, up to a point where any of the Oculus software packages will fail to compile.
So far, it has failed for "oculus-touch-tutorial" and "oculus-worlds".
I've even tried using a VPN to see if I get the chunks served from a different CDN, but to no avail.
