As of 10.4.2 a bug seems to have been introduced. Local servers connected to the network are having difficulty showing up in the sidebar. Under "locations" in the Finder sidebar "Network" icon appears and disappears. My Drobo 5N2 NAS also no longer appears. One can view the "Network" icon by going into the "Computer" home directory where it shows "Macintosh HD" and "Remote Disk", however, drilling into the "Network" directory does not show my local NAS as a connectable server. I have done everything to get this to work including doing a clean install of 10.4.2, to no avail. There were no issues in 10.14.1 release. Is anyone else having similar issues?
