Hi,

My Sectigo (multi-domain) SSL certificate has no issue; bindings are correct; other sub-domains under gatelink.com like testing.gatelink.com work fine on https. Checked DNS settings, checked firewall; the site was working fine a few weeks ago and then suddenly stopped

@KnowMe , do you have "SSL\TLS support" enabled in Domains > example.com > Hosting & DNS > Hosting?

Your login page goes to HTTPS just fine but I've noticed when going to HTTPS for default.aspx it gets me a 302 redirection.



This makes me want to think there might be a rule in your default.aspx that does a redirection from HTTPS to HTTP. If there was an update done to the site you might want to check to make sure there isn't a redirection rule in the code. Look for something like Response.RedirectLocation or Response.StatusCode.
