Hi,
We can see the following error in Fastly Deliver requests. any idea?
“Requested host does not match any Subject Alternative Names (SANs) on TLS certificate”, HTTP/421

Hi @tchelet you’ll need to change the TLS configuration on your configured Host to use a hostname on that origin’s TLS cert. This doc has some more information on the details.

I can see the same. I filled the fields according with the documentation says, but no matter how this part is configured, the response is exactly the same.

I’m doing it in a subdomain for testing, letting the main website without changes. But whatever I do, the response is exactly the same.
