Oct 30, 2019 The Citrix Netscaler version we are running does not support the newest ciphers. The only solution is to upgrade the Citrix Netscaler to a newer release that supports the modern ciphers. For the short term a workaround is to use an older version of Citrix Workspace App / Citrix Receiver. Having the same issue connecting Workspace app on macOS Catalina. 'Citrix Workspace cannot connect to the server. Check your network connection.' MacOS Catalina 10.15.4 and Workspace App 20.02.0.5. And other Mac with Workspace app 19.12.0.23 It has to be an issue with the latest Catalina updates.
There had been an update in Citrix Workspace app (1910.2 for Mac) but since I'm
unfamiliar with this software, I can only point to where it was found that has a
download(?) and leave you there. I've offline work to do that has no bearing here.
Citrix Workspace app 1910.2 for Mac
Release Date: Oct 17, 2019
Compatible with:
Mac OS 10.13, 10.14, 10.15
with download information and button(?) on the same page
uncertain if this may or not be helpful. Has 'end user' info too.
Good luck & happy trails!🌞🌤
