Installation issue for macbook

Hi There, we are experiencing an installation issue on a macbook. The macbook that is installing Bigfix is using Catalina

What the support team did for troubleshooting were:
ping to the Bigfix server - ok
telnet 52311 to bigfix server - ok
reboot the macbook

Appreciate your reply. Thanks!

So you are running 10.15, what version of the client is installed on that system? You need a minimum of version 9.5.14 of the BESAgent to run on that OS.
