ISSUE: Migrating from ESDR2 to 3.0.12.0. Cannot activate radio, error popup says "Lost Connection" after I tap the "Power" icon. Works fine in ESDR2, but not in v3. I followed instructions and F/W was upgraded to v78.8
Operating conditions: SUNSDR2DX on LAN (10.0.0.22) PC is a RYZEN 7 with 16 cores, SSD, 16gb RAM, WIN11 PRO, connected to the same Cisco c3560cx switch.
I can see the unit listed in the First "Device Tree" and I can click connect, but when I try to tap the "Power" button, I hear some relays chatter and it seemingly tries to connect, but I only see the error "Lost Connection" a few seconds after tapping the "Power" icon.

I'm not a programmer, but I've been working I.T. and HAM radio for more than 20 years, so I know there must be something I'm missing and not necessarily a bug.
Thanks in advance!

Hi John.
After you've updated firmware, TRX's IP address was set to default 192.168.16.200.

Ok I've found the problem. Windows Defender Firewall was blocking ports. When I turn off the firewalls I was able to connect using the power button icon.

Too bad I have to go to work now, later I will play with this v3.0.12.1 software.
