Everything works fine for me. Check your internet or call IB, especially if outside US where things may work differently.
I'm using the Hong Kong server and I think the Hong Kong server is down. I cannot connect from March 9, 2020 18:54 UTC.
If you guys can still log in account management, you can switch there from HK server to a different one (I did that a few months ago, no issue logging in today, although what I see is utterly ugly)
