Master nodes stop working after reboot

[GiovanniBarile]

Hello, i managed to configure a HA cluster (3 masters + 3 workers)
After rebooting one (or more) master, the same won't start anymore.

This is the log :

● rke2-server.service - Rancher Kubernetes Engine v2 (server)
Loaded: loaded (/usr/local/lib/systemd/system/rke2-server.service; enabled; vendor preset: enabled)

And when i try to run the rke2 server in debug mode i get this :

sudo /usr/local/bin/rke2 server --debug
WARN[0000] not running in CIS mode

Thank you!

@GiovanniBarile Thanks for the report. Can you curl --insecure https://192.168.42.4:9345/cacerts from that server and also the others and tell me whether it is successful or not (do not share the CA when successful)?
