"Your Connection is not private"

Hey everyone.
Anyone experience this issue? I was able to to preview the setup on SGTM yesterday. Today, I am getting a not secure error for the server domain.

I am using the stape global CDN and CNAME records.

Looks like a problem with SSL on subdomain.

Check if you have changed or deleted DNS records for your sGTM subdomain.

If you are using Stape - support can help with this as well: https://help.stape.io/hc/en-us/requests/new
