Can't Add My Vanguard Account

I there, I am new to Tiller and I am trying to add my Vanguard account to the dashboard but I am getting this notification that says “Unexpected Site Error” Any ideas?

:wave:, @jpbisilliat. Generally errors like this resolve on their own after a few days. So I’d just keep trying. If it’s still not working in a couple days, I’d recommend reaching out to our customer success team via the chat in the lower right corner of the console at https://sheets.tillerhq.com/auth/google - let them know you’ve already tried a few times over a few days. They’ll be best equipped to help you get this resolved.

I also get this error with my Vanguard account when I go to the dashboard, but the account still updates everyday on its own. Not sure why.
