Cloudflare + HSTS (HTTP Strict Transport Security)

Dear team,
We have our DNS on Cloudflare enabled with HSTS.
We have successfully set our domain with * (please refer image below) but now we are facing error of HSTS.

Please see the attached screenshots

Looking forward to getting solution.
With thanks in advance,
AmpliAds Team

Hi! I don’t know how your settings are looking on Cloudflare, but there are some requirements before activating HSTS on Cloudflare.
You can read more about it here: https://developers.cloudflare.com/ssl/edge-certificates/http-strict-transport-security

From what I know the * ( wildcard) subdomain mapping can’t be proxied on the Free Cloudflare plan and this might be the issue why you get the NET::ERR_CERT_AUTHORITY_INVALID error

P.S. I don’t know if the following tip will work. One idea from this tread (if the certificate is issued on Sitejet servers) is to switch the SSL setting on your SSL/TLS app to ‘Full’
