[ERROR] Logstash JDBC plugin - PKIX path building failed

[Rossana (Raquel Acero)]

Hi,

I have an issue with logstash jdbc plugin configuration for MSSQL.

My config file:

input {
    jdbc {
      jdbc_driver_library => "/opt/elastic/drivers/mssql-jdbc-10.2.0.jre11.jar"
      jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
      jdbc_connection_string => "jdbc:sqlserver://0.0.0.0:1433;databaseName=solarwindsbd_rst;"
      jdbc_user => "user_elk"
      jdbc_password => "pass"
      statement => "SELECT SYSDATETIME() \"SYSDATETIME\",CURRENT_TIMESTAMP\"CURRENT\",GETDATE()\"GET\";"
      jdbc_validate_connection => true
    }
}
filter {

}
output {
  #elasticsearch {
  #   hosts => ["clusterECS"]
  #   user => "elastic"
  #   password => "pass"
  #   index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{[alp]}-%{+YYYY.MM}"
  #}
  stdout { codec => rubydebug }
}

I had an error before this one and I dont know if it is related
Error 1:

jdbc - Unable to connect to database.

For resolve this error I change the java.security file
From this:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

To this:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

After this change the error is this:

Do you know which could be the cause of this error??
