Issue Summary

If a roadmap (plans) takes more than 10 seconds to load on Jira, it will fail to load when embedded in a Confluence page.

Steps to Reproduce

1. Create an advanced roadmap on jira (plan) for a new project
2. create 11k issues or more on that project
3. paste the roadmap's link to a confluence page and publish it

Expected Results

The page should load, taking a similar time as Jira does to load the roadmap

Actual Results

The roadmap fails to load, with an error after 10 seconds. The request to /wiki/plugins/servlet/portfolio-proxy fails with a 504 (gateway timeout) after 10 seconds.

Workaround

Workaround 1: Decrease the number of issues listed in the plan, in order to decrease the loading time to 10s or less.

Workaround 2: Change the socket timeout in Confluence to 60000 from UI -> General Configuration.

Just in case this does not work for you if you are working with an older version of Confluence, please add the following parameters in the Confluence setenv.sh

CATALINA_OPTS="-Datlassian.http.socket.timeout=60000 ${CATALINA_OPTS}"

and then restart Confluence.
