I've been getting the CC-503 error for the last few weeks and I can't update any transactions from Ally Bank. I've checked and double checked and triple checked my user name and password. I've Changed my password and continued to recheck to make sure I'm entering the correct information and I'm still getting the error saying "Oops. Did you mistype your login?" I've tried all the suggestions I could find in the community pages to no avail. I've been using Quicken for at least 20 years and have never come across a problem so difficult to figure out and fix. I'm using Quicken Classic Business and Personal for Windows, version R64.35, build 27.1.64.35.
Please help! The last thread for this issue was closed without resolution!
