Tls_parse_ctos_key_share:bad key share

Security
#1

I am using ssl_ciphers 'TLS13+AESGCM+AES128:EECDH+AES128'; in the NGINX.

I have below error.log

2022/02/19 02:52:07 [crit] 21831#21831: *72125 SSL_do_handshake() failed (SSL: error:141CF06C:SSL routines:tls_parse_ctos_key_share:bad key share) while SSL handshaking, client: 65.49.20.68, server: 0.0.0.0:443

Do I need to worry?

This is not a Cloudflare issue

This means a client tried to connect with bad SSL parameters.
