Simulator Hardware
Depending on the type of simulator hardware that you are using and the technology used within the simulator, there may be instances where a shot was not recognized due to many factors. Check with your simulator company to understand why this may be the case.
Connection Issues
In the case where your local network may lose connectivity, this could cause issues with E6 Connect not being able to read the shot data from the hardware as well as PinSeeker not being able to read the shot data from E6 Connect.
