How to fix SERVER ERROR (Code: -10)
This is happening because the SteamVR driver associated with K2VR is disabled, blocked and/or unlisted from the drivers list.
REMINDER: K2VR only works on Windows 10 version 1809 or later. This is due to Win32 API requirements from the SteamVR driver. Even if the driver says it's enabled, it will silently crash on older versions of Windows.
For ALVR users:
If you're using ALVR it will disable other registered external SteamVR drivers by default.
It might throw a warning saying "Windows protected your PC". The app is safe. Here's a VirusTotal scan and the source code.

I'm still having issues.
If the driver is enabled and you restarted SteamVR after enabling it, and you're still getting the server error. Try checking if you have third-party firewall software that could be causing K2VR to be unable to connect to the driver.
