Bad gateway


An issue does not get synchronized and appears in the troubleshooting section with the category 'Bad Gateway'.


Backbone accesses the local and remote JIRA via the official JIRA REST API. Most of the times this error is related to big attachments which Backbone tries to synchronize.

  2. Backbone needs too much time to transfer the attachment to/from JIRA.

Cause 1: Different size limitiations in JIRA:

Cause 2: Timeouts when transfering attachments:

  • ... increase the timeouts as described here. The linked documentation is about bamboo, but also valid for JIRA. Perform a retry afterwards.
