Thank you for reporting an unexpected error on page Netlify App. Please leave this text in place and let us know below any more details that you think would be helpful!
The flow of creating with a template is broken with all templates. All you have to do to replicate is go to: Start with a Template | Netlify CMS | Open-Source Content Management System and choose any template.
Fetching https://app.netlify.com/.netlify/functions/git/repos/wutali/nextjs-netlify-blog-template (or any other template) throws the following:
{“error”:“Error [ERR_TLS_CERT_ALTNAME_INVALID]: Hostname/IP does not match certificate’s altnames: Host: app.netlify.com. is not in the cert’s altnames: DNS:*.github.com, DNS:github.com”}
The error clearly defines the issue but if you need more information feel free to reach out. I couldn’t find a better place to report this issue with a free account. There is obviously no client side solution for this issue, so I’m simply reporting it. Sorry if this is the wrong place.
edit: fixed title and typo
