Question

hd-ningbo.figma.site TLS certificate error in Edge and /bootstrap failure in Firefox

Hello, I’m looking for help with a published Figma site:

https://hd-ningbo.figma.site

The site has started showing browser-specific access issues.

In Microsoft Edge, the site is blocked with:

net::ERR_CERT_COMMON_NAME_INVALID

Edge reports that the certificate is valid in date and issued by Let’s Encrypt (YE2), but it does not match hd-ningbo.figma.site. The certificate appears to identify only IP address 141.193.154.146. Since the site uses HSTS, Edge will not allow me to bypass the warning.

In Firefox, the site fails during loading with:

/bootstrap: NetworkError when attempting to fetch resource

Chrome had previously loaded the site successfully, but Edge is now blocked and Firefox cannot complete bootstrap.

This is a *.figma.site subdomain, not a custom domain, so I do not control DNS or CAA records. Figma Support suggested allowing time for SSL provisioning, but the site was already published and previously accessible, and the issue has continued beyond 30 minutes.

Has anyone else encountered a certificate mismatch or browser-specific /bootstrap failure on a *.figma.site URL? If so, was it resolved on Figma’s hosting/CDN side, or was there another workaround?

Thank you. 

The problems are persisting. I am now also having issues with Microsoft Edge now, and other members of my team also have issues connecting. 

It is frustrating, these issues have only started recently with my app, after a year of no issues, I suddenly have many.
