I’m trying to add a custom domain for the subdomain hjkl for a site on my account but it’s throwing an Error 8000000 and never registering the custom domain for the page (but it still adds it to the DNS management page); I saw in another post from March where the Google Cert wasn’t allowing for IDNs (or something or another) so it has to be manually switch to Let’s Encrypt.
Is someone able to perform that for me if that truly is my issue?
