Well, I’ve never had this happen.
From my home network I am blocked from even accessing lotro.com or ddo.com…every computer / device linked to my home network. Absolutely no issues with any other service / site. Not sure if to call Comcast or SSG, or what good either would do.
If I connect the same devices to the Comcast wifi in my area, I can access lotro.com just fine.
I must have done something to get my home IP address blocked. Brand new PC, 3 days without a problem, then boom at 7 pm last night. I DID make the mistake of trying to install GOG Galaxy, which I quickly deleted but maybe the damage was done.
