inReach not syncing

I've had my inReach for probably close to 3 years now, however I don't think I've ever synced it before. Trying for the first time and the same error comes up no matter what I try - "Error: Failed to read server response."

I've tried different cords, different USB ports, restarting my laptop, restarting my garmin. 

Any suggestions?

Thank you in advance!
