So when you have a connection issue, customer support ask you to create a game consultant. Fine. It's normal.
Then they check the game consultant and tell you "you have an issue with your connection, the game consultant show a failed ping":
Pinging launcher.bethesda.net [54.217.220.128] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
And then you loose hours and days trying to address an issue that doesn't exist, rather than trying other solutions that may solve the problem.
After 3 months they didn't realize yet the issue is that Zenimax firewalls block that ping?
Seriously ?
Please either remove this test, or replace it with a connection test to http port 80 or change your firewall rule to allow ping.
