A. No easy fix for this problem. Please try running Persimus on another laptop.

Q. When I launch Persimus, the phone is unable to connect using the QR code.
A. Very likely, your operating system Firewall is blocking the software. Try each of the following at your own risk:
- Make sure you are running Persimus as Administrator in Windows. Do this by right clicking on the Persimus program and selecting the Run as Administrator button in the menu.
- Disable the operating system firewall.
- Try using Persimus from a different Wifi network. Sometimes, it is the Wifi router which is blocking data flow from your phone to laptop.
