Hello,

Did someone experience following issue while trying to join with a newly created node?
root@c3:~# microk8s join 10.0.0.243:25000/0b217fd5d2e57dc6cadca94af05397f8/f9d68 89e80f1
Contacting cluster at 10.0.0.243
Connection failed. Invalid token (500).

Scenario:
4 nodes cluster planned in Oracle OCI cloud environment.
2 nodes can see each other. The other 2 not at all.

Same subnet.
Firewall rules are fine.
I can telnet to port 25000 of the first node
root@c3:~# telnet 10.0.0.243 25000
Trying 10.0.0.243…
Connected to 10.0.0.243.
Escape character is ‘^]’.
^]
telnet> quit
Connection closed.

Cluster version

OS version

Any advise would be appreciated.
