Hello I'm halfway through my uni dissertation and stumped as I can't for the life of me figure out why the designated leaf nodes can't join the master node's cluster? I'm following the documentation correctly from the ubuntu tutorial on microk8s and the official microk8s documentation page here: https://microk8s.io/docs/clustering
I can issue the add node command on the master node fine, the join command I paste into one of the leaf nodes in order to join them into the cluster to become leaf nodes.. fails with error code 500 but isn't helpful. Could anyone point me in the right direction? I'm using Ubuntu server for ARM.
I am using carrier grade NAT, a 4G router with a 4G simcard inside; could this be the cause of the problem? Thanks for your time.
