Thanks for your reply Shymae, but I am way beyond the suggestions you have sent. 

Both in a new company file, or within my active company file, trying to add or create a new citi feed fails. 

I have checked the citi website and there are no issues with my credentials, third party access permissions or any posts regarding any service disruption. 

So no my questions is: Are you getting complaints from others in the community? At this point I have to believe that Intuit is aware of the problem and attempting a fix. I further believe that most likely Citi changed something on their back-end and do not inform Intuit Engineers. I would really just like to know that Intuit is aware of the issue and working to fix. 

The attached file shows the error you get when trying to create a new bank feed with CIti
