No info at all via the quickencommunity ticket I'm following..but.. I got through to someone knowledgeable at Wells Fargo and my problem is solved!! The trouble was special characters in passwords. Oy!! Apparently, Wells Fargo allowed damn near anything [and I've had no trouble with logging into my account via their website] BUT: Quicken doesn't like "damn near anything" and so things get messed up when it relays my password to Wells Fargo. [the tech support person said this same thing happened when they expanded passwords to 32 characters -- that works fine within WF and on their website, but Quicken couldn't [can't?] handle passwords that long]. When I fixed my password not to have any special character not on the list at WF it all worked.
It is a little hard for me to figure out what was going wrong. I'd assume that if I gave Quicken the *wrong* password, I'd get some useful "your password isn't correct" error or something like that. In this case all I got was "we can't handle your request at this time, please try again later" from WF. Anyhow, my nearly-four-week hassle is, for the moment, fixed.
