Stim opens a series of both TCP & UDP ports on your router for your device to communicate directly with your Cloud PC, making your connection a straight line and as low latency as possible.
Sometimes however "UDP Hole Punching" fails, and so we create and route your stream through a proxy. This proxy is often forced to route traffic over TCP. This slows things down as TCP has higher latency than UDP.
The stream latency and quality may be great for you through a connection proxy, but ideally you could connect directly to your Cloud PC in a straight line (without needing a proxy) and use UDP which offers lower latency.
Some things you can try to resolve this error:
- Refresh the stream webpage - Each time you reconnect Stim selects and tries a different port selected from a range of UDP ports. It may be that your router was blocking the port being used.
- Check your router to see if your firewall is blocking UDP traffic. To troubleshoot, try a different ISP such as mobile hotspot.
