I cant connect Masso link to the G3. I’m on 5.07 with link 2.12. I cant use 5.09 yet as the notes say dont use it if you are using a Type 2 tool changer. I just installed the ATC using Type 2 tool changer. Has anyone figured out how to connect Masso link without getting the blinking connecting forever? I can see the G3 connected to my network. Thanks ---

A quick check, turn off your Windows Defender Firewall for a minute and try. If it connects, you need to add a rule for it in the Firewall to allow it through. This is what finally got me connected.
