I noticed that event though Quicken was connecting, it wasn't updating. I started a new file as other accounts were doing the same. Everyone was fixed in the new file, except Home Depot. Looking at the other threads and trying with no luck, I called Home Depot support. The Agent I talked to said I needed to go to
https://homedepot.com/mycard
and make sure my login was established there Once I did that I was able to establish my connection using my new login/password for the Home Depot Consumer Credit card (now updating properly) and not my former account information used before that used the old (still needed for their home site) login info.
