If the Shadow launcher is unable to connect and start the video stream, the launcher will display one of the following error codes: L:100, L:101.

Solutions:

1. Try starting your Shadow again. It's possible your Shadow timed out on the first attempt, but will successfully connect on a second attempt.
2. Shut down your Shadow from the launcher before starting it again. To perform this action, click the Help icon, then click Shut Down Shadow. Wait 2-3 minutes, then try to start Shadow again.
3. If Shadow still displays one of these errors, contact Shadow Support and send logs.
