Https:// on Root Domain not Forwarding to https://www. version of site

I changed my DNS so the www has the CNAME and the root domain has the two A Records.
https://www.sigmacomputing.io. - Working
sigmacomputing.io - Working
www. sigmacomputing.io. - Working
https://sigmacomputing.io. - not working
When I got to https://sigmacomputing.io I get a message that they failed to establish a secure connection. On Chrome is says SSL protocol error.

Any idea what may be the issue?

ETA: Looks like this was an issue on Webflow’s side that is now resolved with the help of support.
