I am having the same issue… I’m using Cloudflare. On my hosting account, Siteground, I setup a new Sub Domain, online.newhavenhappenings. I created an SSL cert for that subdomain.
I proceeded to Cloudflare and changed the settings as provided by Glideapp.
_glideauthid.online TXT 9xskfYZGrQ9RFkdhPHWS
online CNAME custom.glideapps.com
I cannot get the CNAME to verify. Only the TXT.
Can someone help…
