Hi! I recently posted this issue regarding my jenkins configuration and was referred to this forum instead. About 2 weeks ago, we upgraded jenkins to the latest LST version (2.401.2) plus upgraded all our plugins to their most recent versions. We use the GitHub plugin for integration with our repos. After the upgrade, whenever I restart the jenkins.service on my instance, the configuration for the github plugin fails to reload. the following exception is visible on the journal logs:

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 (which is super annoying):
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!

I started with a fresh Jenkins instance, with nothing but the recommended plugins, plus the Github plugin installed. I then started installing all plugins we use in production (one by one) until I bumped into the error. I then started over and installed only the Github plugin plus the conflicting plugin, to make sure I was getting the right one.
