Bluefin upgrade broke apps. Tried to revert and now Kubernetes fails to restart

[j.lanham]

Tried to revert to prior boot environment after upgrading to Bluefin because applications won't start. On reboot to prior version, Kubernetes fails to start with following error.

Failed to start kubernetes cluster for Applications: Cannot connect to host 127.0.0.1:6443 ssl:default [Connection reset by peer]​

Anyone seen this?

Restarted with the bluefin boot, and it came backup with the app not restarting again. Well, apparently this is a one way upgrade.

Follow this checklist thread, I was sure you will have other issues.
This one is a new issue, probably the iptables rules are messed now, since you cannot properly revert back to Angelfish. It could also be that ix-applications dataset is messed, you could try to migrate the dataset and apps to a different pool. I would suggest to fix all issues listed into checklist thread and then upgrade to Bluefin.

This the output for my iptables in Bluefin:

Code:

What is your iptables output?
