SSL error on new retool subdomain

Hiya, I signed up for retool about 1.5 hours ago, and was well on my way into building my first app, when suddenly I was unable to run one of my queries (I was getting "Failed to fetch") in the console.

I refreshed the retool page, and saw an SSL certificate error, and now that is consistently there. I thought it may be related to some lag in setting up my new account, but it's been about 30 minutes and I can't access my subdomain.

The error I'm seeing in Chrome is net::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED.

Is this a widespread issue?

Update: It's finally working again, so never mind!
