This error message appears on Windows computers on Agent UI.
Agent UI on a Windows is just an additional component to Resilio Connect Agent service, the main agent process. Agent UI runs as a separate process on a Windows computer. Two most common reasons causing this errors are:
- The Agent service is not running. You can open Services and start Resilio Connect Agent Service.
- The Resilio Connect Agent Service is not installed. To fix it, download the MSI installer from download site (not the .exe!) and install it.
