Nginx configuration error
The line ssl_ecdh_curve X25519:prime256v1:secp384r1:secp521r1;
in the nginx configuration causes the error nginx: [emerg] Unknown curve name "X25519:prime256v1:secp384r1:secp521r1" (SSL:)
for me.
I tried researching this error to fix it, but couldn't find anything helpful (that I could understand at least), so I'm not sure if this is an error with my server set up specifically or a problem with the nginx configuration provided.
