Mint Connectivity Failure - Primis New Digital Banking (Error 189)

I am unable to add my Primis New Digital Banking Checking & Savings.

 

Despite authenticating my username and password and generating a six digit SMS authentication code, I receive the following message:

 

“Something unexpected happened and we couldn't connect to your bank.“

 

I am instructed to verify my login credentials and to retry. (189)

 

Has anyone encountered this error or successfully connected their Primis New Digital Banking accounts?
