It's loading just fine here. The Pogo servers are probably experiencing regional issues.
I am having the same issue. Been a few days now. I wanted to check on any challenges I had for the 3 games they are retiring next year but have been unable to.
I've ran Ccleaner and changed my location with my vpn, but still that error.
I tried 2 other browsers no go. I then loaded my second account and it works fine on firefox, edge and chrome. My first account won't load on different comp either.
