When I navigate via either Safari or Chrome (from my MacBook) to: https://appstoreconnect.apple.com/access/users/sandbox I get the red error message at the top of the page: "Something went wrong. Try again later". Using the browser debugger, I see that the error is a 502 Bad Gateway error. Sometimes, I can view my Test Accounts, but over the last couple of days, I get the "Something went wrong..." error just about every time I attempt to access the Test Users. If I am lucky enough to load my list of test users and then attempt to modify one of them, the Save operation fails with (you guessed it) 502 Bad Gateway. I'm relatively new here, so if I've missed something and there is a crucial step that I need to do to get some work done, please enlighten me. This has worked in the past but is failing pretty consistently now. Super frustrating.
