Error -6200 means the Parsec web app failed to establish a peer-to-peer connection to the host. The most reliable fix is to connect using the native Parsec app instead of the browser.
- Download the Parsec app for your device.
- Install it and sign in with the same account.
- Connect to the host from the app.
Why this happens
The web app streams over webRTC, a browser standard for low latency video. The native app uses BUD, Parsec's own streaming protocol, which is both faster and more reliable at negotiating peer-to-peer connections. webRTC fails to negotiate a connection more often, and error -6200 is that failure.
