NPE Error Code: 0x8004500b,0

When I use the Norton Power Eraser tool everything is working fine except when I am trying to run the Unwanted Application Scan. It just stops because it can't access the Symantec server and gives me the Error Code: 0x8004500b,0.

I have never had any problems using the scan earlier, but I have gotten the same Error code for the last 2 weeks.

Can someone help me locate the problem and tell me what issue the  Error Code is pointing to.

All the other Symantec/Norton products/tools I use is working fine.
