Good morning, @penstruck. 

Welcome back to the QuickBooks Community! 

A "HTTP 403 error" in QuickBooks Desktop (QBDT) means the program can't access online services, often due to incorrect internet settings, firewall restrictions, or a damaged file in the CPS folder. To fix it, check your internet settings to disable the proxy server, verify firewall rules, run a malware scan, or repair the QuickBooks installation. 

As for the OLSU 1024 error, you might get this error if: 

• There’s a problem with your bank
• You have alerts on your online bank account you need to acknowledge
• Your bank changed their service offering to Web or Direct Connect
• You have an inactive bank account in QuickBooks with online banking
• Your bank’s info isn’t updated on the Financial Institutions Directory (FiDir) in QuickBooks
• There might be a problem with their servers
• There’s a problem with your internet connection
• There’s a problem with one or more bank accounts in your company file
• The file from your bank isn’t compatible with QuickBooks
• You’re using a version of QuickBooks we don't support
