Jira server is not Reachable Due to Peer Not Authenticated

Jira server is not Reachable Due to Peer Not Authenticated

Refer to the steps below when using the plugin with Jira Server or Data Center instance with self signed certificate.

We recommend using Openssl that comes with git installation when running on Windows to not to risk by downloading 3rd party openssl implementaions
(in all commands below instead of jira.host.url substitute your Jira server url)

 Run cmd as administrator on Windows

  1. cd C:\Program Files\Git\usr\bin\

  2. openssl s_client -connect jira.host.url:443 < NUL > c:\tempCert\jira.host.url.crt

 After saving the certificates in Windows, edit them and delete everything before the "BEGIN CERTIFICATE" line and everything after the "END CERTIFICATE" line. This step is not required for Linux.

Java 9+

So with Java 9 (aka Java 1.9) or later, simply use

keytool -importcert -trustcacerts -cacerts -file c:\tempCert\jira.host.url.crt -alias jira.host.url

Earlier Java versions

With Java 8 (aka 1.8) or older, you must specify the keystore location like so

keytool -importcert -trustcacerts -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -file c:\tempCert\jira.host.url.crt -alias jira.host.url

With Java 5 (aka 1.5) or older, the -importcert option did not exist. It was called -import, but otherwise it's identical. So use

keytool -import -trustcacerts "%JAVA_HOME%/jre/lib/security/cacerts" -file c:\tempCert\jira.host.url.crt -alias jira.host.url

 The trust store is located in the following directories:

  • Windows/Linux: %JAVA_HOME%/jre/lib/security/cacerts

  • Mac OS (not supported): $JAVA_HOME/lib/security/cacerts

If keytool prompts for a password, the default is 'changeit'.
