ah HAH! I found it.
"[b]ipc connection error, connection refused[/b]" has started occurring for me when the Synergy [b]service[/b] is [b]stopped[/b].
Note that Windows has [b]processes[/b] and [b]services[/b]. Once Synergy is installed, a Synergy service is always running, regardless of whether or not you are currently using Synergy.
- In the Task Manager, go to [b]Services[/b]
- Find the [b]Synergy[/b] service
- Right click, and select [b]Start[/b]
I am not sure why this service stopped, but hopefully starting it will immediately restore functionality. Let me know if this work
