nginx and tomcat ssl issue - SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

Question

Since my site ssl cert was expired I've renewed it and added new cert to keystore, but after that I am getting 502 when called the site url. Below you can see nginx config and tomcat configs for ssl.

Error I am getting in nginx error log is

SSL_do_handshake() failed (SSL: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure) while SSL handshaking to upstream, client: 120.6.20.134, server: app.somewhere.com, request: "GET /favicon.ico HTTP/2.0", upstream: "https://53.10.10.10:8443/favicon.ico", host: "app.somewhere.com", referrer: "https://app.somewhere.com/board/index.jsp"

server nginx version: nginx/1.12.1

Answer 1

Found the issue, the certificate was imported to the wrong key-store. So I've created new key-store using certificate and private-key that I had using following commands.

create new keystore

openssl pkcs12 -export -in cert.crt -inkey private-key.key -certfile cert.crt -name "tomcat" -out keystore.p12

convert keystore to jks format

keytool -importkeystore -srckeystore keystore.p12 -srcstoretype pkcs12 -destkeystore keystore.jks -deststoretype JKS

Then set the keystore.jks path in tomcat server.xml
