UPS keeps disconnecting and reconnecting

My UPS is connected by USB cable to my readynas RN104. I regularly get the message: Error communicating with UPS UPS (). Then I usually get a message shortly after: Communication with UPS UPS () is OK.
This happens several times a week.
Im using version 6.5.0 but also had this issue on previous versions. I have tried using different usb ports on the Readynas.

My UPS is Manufacturer: APC, Model: Back-UPS ES 600G,

An example of the log entries I see are:

Tue May 24 2016 4:19:15		System: Communication with UPS 'UPS' () is OK.
Tue May 24 2016 4:19:06		System: Error communicating with UPS 'UPS' ().

Any suggestions on how to fix this? Thanks.

I also tried using a different usb cable to connect the UPS to the ReadyNas and am still having the same issue.

Any suggestions?

Thanks.

  Hi jhyland,
  
  Kindly send us the logs so we can have a look. Also, could you tell us if you have tried another UPS?
  
  Kind regards,

    Hi Brian - I have tried a different USB cable and tried using different USB ports on the readynas and I get the same result. I've plugged the UPS into a laptop and the APC Powerchute does not find any issues with the UPS. Unfortunately, I do not have another UPS to try. What is the best way to send you the logs? I'm not sure I want to post them publicly (not sure if they contain private or sensitive data).
    
    Thanks for your help.
