Environment
A gadget is added in Jira, which times out on request to external system
Diagnostic Steps
If the response from external system serving gadget content is longer than 5000 ms, the gadget will time out
The default is coded in com/atlassian/gadgets/util/HttpTimeoutsProvider.java
Cause
The default HttpTimeout in threads making request from gadgets is 5000 milliseconds and the Confluence page is too large or is loading external elements and can't be pulled by Jira within 5 seconds.
For example, the Confluence page may have a long-running Jira filter.
Solution
Workaround
Increase the HttpTimeout as needed (10s for instance) by adding -Dhttp.connection.timeout=10000 to JVM_SUPPORT_RECOMMENDED_ARGS in setenv.sh.
Notes
Please be cautious when using this parameter as it will extend the life of internal threads making external requests. The hardcoded value of 5000 milliseconds is designed to prevent long-running threads. We would advise against changing it unless the change is tracked and documented, as it may impact performance of the Jira instance.
