New Domain + Quick Start = SSL_ERROR_NO_CYPHER_OVERLAP

I’ve created a new account / domain for the trial and am trying to work through the initial quick start (I chose the React app). When I click the login button and land on our new domain to begin authentication, the browser immediately barks back:

Secure Connection Failed

An error occurred during a connection to (our new auth0 domain). Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

This is in Firefox, but Chrome and Edge throw similar errors. Any ideas?

Resolved! I fat-fingered the domain attribute in the tag.

Correct: dev-ourdomain.us.auth0.com
I typed: dev.ourdomain.us.auth0.com

Obviously, a one-character difference that has very real implications as to what domain is correct and in charge of the cert.
