For what it's worth, the
Capital One repeating reauthorization request and CC-501 error has been haunting me since late December 12, 2021. Quicken's instructions to
Deactivate and Reactivate the account did not fully work for me. Instead I did this:
- Right Click Capital One account->Edit/Delete->Online Services->Reset Account. (no account data will be deleted.) (this process attempted to but did not enable me to re-authorize the account successfully). I then deactivated and reactivated the account. Still no success.
- This worked: In the Accounts list, I clicked the + sign to add a new account. I followed the prompts, but instead of naming a new account, I linked to the existing Capital One credit card account.
On completion, Quicken downloaded all transactions since the last successful connection back in December 2021. Updates are working.
I have no idea how or why this works, and I don't know why Quicken Support does not mention this simple but effective procedure for fixing the CC-501 error (This error is accompanied with the message that Quicken Servers are unreachable and to NOT contact the financial institution.
I posted this info for future reference should others encounter a similar issue.
