Trying to view vault on 1password.com - continually asking to login

I am trying to login to 1password.com so I can view the contents of a vault.  I successfully login 1pw.com but when I select All Vaults I am brought to a page that asks for my password. I enter it a couple of times and then this error message starts appearing.

I am copying & pasting from the 1PW app (nightly build) on macOS into the Safari browser.  

Any suggestions?
