Enable TLS 1.2?

Unable to Connect to Home Assistant from iOS through proxy - Even after trying all troubleshooting from similar posts

So I finally figured out the issue. It looks like iOS will not connect to HA over TLS 1.3. TLS 1.2 must be enabled as well. With the following TLS config, it works: ssl_protocols TLSv1.3 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5; ssl_session_cache shared:SSL:10m; ssl_ecdh_curve secp384r1;
