Hi,
I know that there is a Vanguard outage showing in the outage dashboard for a while but my Vanguard account has been working fine until today. Now, I am getting this error " We’re unable to add your account because this site is blocked. Please contact Vanguard’s customer support to fix." along with a banner that says “Vanguard access is blocked”. Anyone else have this issue? How did you resolve this? Almost all my retirement accounts are on Vanguard - so I am pretty alarmed.
There was a discussion on here a month or two ago that established that Vanguard limits third-party aggregators to (roughly) non-trading hours in the US.
