Connection timeout is used for establishing connection between JIRA and TeamCity. If the connectivity between two instances is intermittent, you can set the higher connection timeout for the add-on being able to successfully establish connection to TeamCity. If you set the lower value, the add-on will terminate the current connection attempt and start a new one. If the connection is slow or ping is high, the add-on will require more time for establishing connection to the server. So if you set the lower value, the add-on may not to be able to successfully connect to TeamCIty and start data indexation. Talk
