I have a suspicion that your issue might be the same as this: https://github.com/hexparrot/mineos-node/issues/150 (on attempts where you have updated the mineos webui via git)
Lately, some changes have been made to fix a runaway npm module called “fireworm” in the server detection process. These changes, however, hinge on a more recent version of node than you’re using, which is a pre-release v0.10.31.
Are you able to update your jail to use a release-ready version, 4.0.0+? I think it will fix your problem immediately.
Based on your logs, your git repo is older than at the very least, October 15–this is the point when the logs self-reported what commit was being used.
