Quickbooks Online not connecting to American Express

[Kevin Polite]

Anyone else suddenly lose their Quickbooks Online connection to American Express? QBO can't seem to figure out why I keep getting error codes 102 and 103. Both have to do with connecting to American Express using your Amex sign on. I've been connecting for many years, but it just stopped working, though this happened about 4 years ago and I changed my password and that worked. I've contacted both QB and Amex and neither seem to can find the answer.
