Auth stalls after submitting password

After submitting my (LDAP) password in the New Login Experience, the authentication process stalls. I see a animated throbber along with the name of the site I’m attempting to access, but I never reach that site. And if I load the site again, I’m not signed into it.

That happens for multiple sites I’ve tried to access this morning, including this one! Fortunately, I found a container in which I’m already signed into this site, so I’m able to post this topic.
