I have a large problem with connecting to Diablo 3 and have tried to trace the issue. I have found two different ways in and both have an issue.
Can you please check ae1-br02-eqam1.as57976(.)net and ae1-br01-eqam1.as57976(.)net. They are both located inside your telia network directly after the gateway.
They do give a lot of latency up to 5.000ms (yes 5.000ms). In worse situations, ae1-br01-eqam1.as57976(.)net don’t replay all. (Full packet loss.)
I’m also on Telia’s network.
