Unable to download UBS - Now have ERROR Code 16503

Now getting Error 16503 on all UBS Accounts.

3 convo w/UBS Support, the OFX file is correct. We have rest passwords, reset UBS OFX account authority, restarted computer, verified account names.

NO recent software upgrades for any devices

READ article saying to turn off BILL PAY in account settings. Like others said, I dont have that option displayed
