Having trouble connecting M32 Edit to M32


I see the M32 in the M32 Edit Setup window and can select it, but when I hit Connect nothing happens.

 PC and M32 on the same network, connected via ethernet switch.

M32 IP address 192.168.10.xxx
M32 subnet mask
PC IP address 192.168.10.xxx

I can ping the M32 from the PC and it replies quickly.
Win 10 Pro on PC
V4.06 on M32
V4.3 on M32 Edit

I allowed M32 Edit through the firewall to no avail.
I tried running M32 Edit as Admin to no avail.

Please help me figure this out. Thanks in advance!
