The add-on uses the proxy properties loaded by Java Virtual Machine (JVM) on startup of JIRA.
If JIRA is configured to use a proxy, it tries to connect to TeamCity via a proxy even if the TeamCity server is in the same network. The proxy server could block this connection as shown below.
You can connect JIRА to TeamCity directly by using the two parameters, as follows:
|true / false||If true, the add-on will try to directly connect to all Teamcity servers without using the proxy server.|
|host name||If specified, the add-on will try to directly connect to the specified TeamCity servers, the proxy server will be used for the rest of hosts.|
|For the details on JIRA startup options, refer to the How to Configure an Outbound HTTP and HTTPS Proxy for JIRA page.|
