From another system, I can see that the xml file is redirecting to duke university (can’t post URL). However, when I try to reach that URL, I get “Something went wrong”. I did some looking around and found a link to a HTTPS archive URL. From there, I don’t see any directories for graylog. How can I get this package installed?
Yes, there is a transparent proxy that only allows whitelisted sites. There is an entry for .graylog2.org. Are there any other domains that need to be whitelisted to allow the install?
