Increasingly unreliable connection to Prosperity Bank USA

Fort worth Jim

I'm running Quicken Classic Deluxe Version 8.5.2 (Build 805.60133.100) on MacOS 26.4.1. I'm increasingly experiencing connection problems with Prosperity Bank USA when attempting to connect using Direct Connect. Based on the reports of others in this forum, I attempted a disconnect/reconnect. I'm unable to reconnect at all; when I try, Quicken returns an error 16503. Advice/suggestions/fixes are greatly appreciated.

Hi @Fort worth Jim,

Thank you for reaching out. These errors indicate that Quicken did not receive the expected response from your bank.

If you haven’t signed up for the bill payment service provided by your financial institution but have enabled that service in Quicken, you may see this error. Please make sure your account settings in Quicken match the services currently provided by your bank. Here’s how:

1. Open the register for the affected account.
2. Click the Settings button in the bottom right corner. 
3. In the Account Settings screen, click Bill Pay.
4. In the Bill Pay tab, review if the Bank Bill Pay status is set to On. If you don't have Bill Pay enabled with your bank, but the status in Quicken is On, you will need to turn it off.

If the steps above don’t resolve the issue and you’ve been experiencing it for more than 24 hours, I recommend contacting your financial institution. Since Quicken doesn’t have access to the bank’s servers, resolving this may require speaking with an online services specialist who handles transaction download issues, as noted in the support article.
