Morgan Stanley Wealth Management Can't Import

Attempts to import from Morgan Stanley Wealth Management not working. I can log onto the website fine with the same credentials, but cannot do the import. I get an error message asking me to check my internet connection! Obviously the internet connection is working, as I posted this, accessed MS online through a browser (after it didn't work in TT, so no it's not a "log out of your account first problem). Is this because MS requires devices to be verified with a texted code? Firefox browser device is authorized on this same computer.
