Quicken stopped connecting to US Bank yesterday which causes a failure and freeze during One Step Update. Resetting the account connection sent me to US Bank which tries to set up the connection through Intuit. This fails. I contacted US Bank and they say they are aware of the problem and trying to resolve it through Intuit.
I don't know whether Quicken still connects through Intuit since it broke off, but it has been working with the US Bank authentication for some time until yesterday. Apparently US Bank has done some major changes with the way its online banking works (I had to disconnect my VPN to prevent US Bank from locking me out of my account when I logon through my browser).
Hopefully, this can be resolved soon.
