Citi bank (costco) not loading

Trying to add this new account. It just keeps trying to connect with no luck. I have tried a few times. Should I maybe try again tomorrow or other ideas?

It just worked tonight at 20:40. Must have been a glich on Citi’s end.

Trying to add my costco Citi visa to my accounts and I’m getting a 403 error on the auth pop up. Anyone else have this problem?

I can’t speak to that particular error per se but try a couple of times and you may want to try re authenticating your tiller session, if none of that works then i would reach out to tiller support in the console on the chat option so that they can assist you 1 on 1 and look at your particular case
