      We are mounting an external EBS volume on AWS containing our jenkins data to /mnt/data. I've checked file permissions are correct and the jenkins user can most definitely read/write to this location. Because the configuration does not re-load, after each restart I need to go to Dashboard > Manage Jenkins > System and input my Github server configuration (see image).

      I've tried removing the file and re-configuring the plugin. After this /mnt/data/github-plugin-configuration.xml gets regenerated as expected. However when I restart it still fails to load.

      I recall seeing this issue pop up with an older version of this plugin, but I cannot find the link. Any help solving this is appreciated!
