Hi All,
Today I started noticing some of my High Sierra machines throwing NSURLErrorDomain error -1100.
Not all of my machines are showing the error, and the machines that are showing the error are able to view the catalogs via a webrowser.
After doing some digging, it seems to only be affecting machines that have installed Security Update 2020-005 on High Sierra. Mojave and Catalina systems aren't affected and High Sierra stations that haven't installed the update are still showing updates as available.
Anyone else having issues?
