Logging into Goldman Sachs Ameriprise Line of Credit

I've recently established a LOC with Ameriprise and set up login to their site saving all information into 1Password as I do with sites I'll log into frequently. All worked fine the first time.  Then I logged out and tested the process by trying to log in again.  I got a 401 Error code from the Line of Credit site.  This happened numerous times.  I spoke with Customer support at Goldman Sachs and worked through many iterations including creating new passwords and cleaning my Chrome Browser history numerous times. But each time I logged out and tried to login again I got the same error code. 

Ultimately,  I removed all login info from 1Password, set up a new password for the site and did not save it in 1Password which I had turned off.  Login, sign out and login again all worked.  Then I added the site back into 1Password and the same error code appeared.  

It seems that some interaction between 1Password and this site is the issue.  Does anyone have insight as I would like to use 1Password as I do for other sites
