Norton Security on Windows 7 LiveUpdate error

I have Norton Security 2015 (version 22.1.0.9) installed on a Windows 7 64-bit machine. Everything was working fine and all of a sudden LiveUpdate fails with an error code of 8921,253 (Unable to connect to Live Update server). Internet connection is working on the PC and I spent about half a day with Symantec techs doing remote debug. They could not resolve my problem. I was digging through the log files and I found one at C:\ProgramData\Norton\.....\Lue\Logs\Log.Lue and here's a snippet of log messages

It appears that LiveUpdate is looking for a "mini tri" flag file and is unable to download it. Anyone know anything about this mini tri flag file and as to why Windows 7 LiveUpdate is unable to find it? LiveUpdates on other Windows 8 machines are working fine

 

Thanks for any suggestions!
