Error Code 522: Bank Transaction Feed not working for some reason

Hello, 

My Cloud Banking Transaction feed is not working for some reason. 
I haven't changed my password or have done anything weird with my bank account.
My transactions haven't came in since the 6 of June. 

It says some kind of error has occured. 

 I click on it and get an error code 522. It also tells me to: "Try again -> Initiate MFA Request". 

How do I initiate an MFA request? I don't see a button for that?  How do I fix this?
