Oh, there seems to be a load balancer in front of your site. AFAIK the error you are seeing comes from GCP. I’m not sure how that stuff works or how you’ve configured it to work, but it might have problems with the ECDSA certificate. Are you even using the Let’s Encrypt certificate from Discourse? It looks like the load balancer is terminating the TLS connection.
