The most common issue is that your app is unable to connect to your computer. There are many different things that can cause this problem, which is out of our control. Please try these suggestions before contacting us.
In the app, remove all saved servers and re-add them. This should solve any issues where your computer's network address has changed.
Check your WiFi network. Make sure your computer and smartphone/device are connected to the same network. It doesn't matter if your computer has wired internet as long as they are connected to the same box!
Update to the latest version. Make sure both your app and server are updated to the latest versions. Follow our Update tutorial for more details on how to update.
Check your firewall. If you are using Windows try our Windows Firewall tutorial to make sure your firewall is configured correctly. If you are using other security solutions, make sure ports 9512 TCP and UDP are allowed, and port 9511 UDP (for automatic server discovery).
If you are using Mac try our Security & Privacy tutorial to setup the firewall.
Perform a ping test. There might be something else blocking the communication between your device and computer. Follow our Ping Test tutorial to check the connection.
If your mouse isn't working (or if it's sluggish/jittery), you can try reinstalling the server without the driver. Have a look at this tutorial.
If all fails. Restart your computer. Also try reinstalling Unified Remote (app and server).
