Troubleshooting

I'm on Linux, with Nvidia proprietary drivers, and Drop won't launch

Add WEBKIT_DISABLE_DMABUF_RENDERER=1 to the Drop .desktop file:

1. Open /usr/share/applications/Drop\ Desktop\ Client.desktop with your preferred editor
2. Add WEBKIT_DISABLE_DMABUF_RENDERER=1 before drop-app on the Exec=drop-app line

"Server's and client's time is out of sync..." or HTTP 0

The server and client must be within 30 seconds of each other for security reasons. Drop uses short-lived tokens to authenticate securely, and they are valid for those 30 seconds. If you are the server administrator, please ensure both your server and client have the correct time. If you are a user, please double check your own system before asking your admin.
