Problem
Trying to create an Application Link from JIRA to Bitbucket Server can result in the following ERROR:
The host is unknown. Verify that the URL is correct.
And when attempting to create the same Application Link from Bitbucket Server to JIRA the below error may occur:
The Remote application is not able to connect to 'Repository Manager'(Bitbucket Server) by using the URL 'https://<HOST_NAME>.<DOMAIN>:8443'.
Cause
This happens because JIRA doesn't have the Bitbucket Server Certificate on its Trusted Certs (Cacerts file).
Resolution
To successfully connect JIRA with Bitbucket Server using the Application Links it is needed to import the Bitbucket Server Certificate into the JIRA Server Cacerts file.
Export the Bitbucket Server Certificate:
1$JAVA_HOME/bin/keytool -export -alias tomcat -file file.cerImport the Bitbucket Server's Certificate into JIRA Server Cacerts file:
1$JAVA_HOME/bin/keytool -import -alias tomcat -file file.cerConfigure
JAVA_OPTSvariable with the path to Cacerts file:1export JAVA_OPTS=-Djavax.net.ssl.trustStore="$JAVA_HOME/jre/lib/security/cacerts" -Djavax.net.ssl.trustStorePassword="changeit"ℹ️ If the JIRA instance is also configured to use HTTPS thesame procedure has to be repeated on the Bitbucket Server (export JIRA Certificate, Import JIRA Certificate into Bitbucket Server Cacerts and configure the JAVA_OPTS variable on the Bitbucket Server).
