The client connecting to nginx server didn't like something during the SSL handshake and closed the connection. Enabling more verbose logging can reveal more details why this happens.


I recently ran into this issue while attempting to enable mTLS and if like me, you've defined ssl_client_certificate make sure you certificate ends in *.crt not *.pem
