One Click Support - Checking Update

Hi, 

 

I'm running product version 18.6.0.29 One Click Support appears to stick on "Checking Updates". Running a packet capture the application appears to direct the traffic to IP 216.82.243.91. However the server on this IP address responds constantly with [TCP Window Update]. (see below)

This appears to run constantly with the same responce from the server. DNS query's are: 

 

417.472297 192.168.206.133192.168.206.2 DNS 81 Standard query A tificocs.symantec.com

The One Click Support does not update. 

 

Any guidance will be great.
