You can tell that you have set up a Custom URL in Google Workspace by adding a CNAME(ghs.googlehosted.com) for the Sub domain (Mail) . However, there is an error saying “SSL handshake failed” when we searched with (mail.tap5050.com) . This should be redirected via HTTP (as Google only supports HTTP connection). But as a new update in Cloudflare it is being redirected via HTTPS .
I don’t have a solution for you, but I can confirm that the redirectm to ghs.googlehosted.com is failing using HTTPS. I had some aliases pointed to that Google canonical name that now fail if I specify the HTTPS scheme. If I just type in the hostname it works. My records do not happen to be in any of my Cloudflare DNS zones.
One thing that may help is changing your CNAME from to . Right now when I look up your mail.tap5050.com hostname, I see A records instead of a CNAME. This is caused by having the Cloudflare proxy enabled. If you set that record to DNS Only, Cloudflare will return a CNAME. This may help. If it does not work in a regular session after making that change, test again it an incognito browser session to rule out any browser cached settings.
