SCALE 21.08-BETA2 Failed to start kubernetes cluster for Applications

OS Version:TrueNAS-SCALE-21.08-BETA.2
Mobo: Gigabyte B450M DS3H V2
CPU: AMD Ryzen 5 3600 6-Core Processor
Memory: 31 GiB

Upgraded my server from 21.06 to 21.08. I could install apps prior to the upgrade. Now, when I boot the system, I get the following alert:

Code:

Failed to start kubernetes cluster for Applications: 52

How do I manually start kubernetes if kubectl is not installed?

Weird, would need more details on the specific reason that kubernetes isn't starting. If you look at `systemctl status k3s` is there any other obvious errors in the log output?

I have subsequently found the problem. I installed tailscale (a nebula vpn) which started interfering with a bunch of services. After removing it, things returned to normal. My next question is how do I request the proper integration of tailscale? This would greatly simplify secure communications between two of my sites as it does not require poking holes in my firewalls or setting up a VPN server out on the internet.

@etrigan63 thanks for posting this I've been beating my head ageist the wall trying to figure it out. I was about to give up
