Hi!

I am trying to setup metallb on my Raspberry Pi microk8s cluster, but when I do “enable” I get this output:

kdc@kdc-node-1:~ $ microk8s enable metallb:10.10.0.240-10.10.0.250

Does anyone know how to solve this? :slight_smile:

Thanks in advance!

I changed the configfile to Ignore fails, seems to work. I have now got External IP on my load balancer. Te nodes have the ip range 10.10.0.150-10.10.0.150 and I set my loadbalancer to 10.10.0.240. But I cannot seem to be able to reach the loadbalancer from my local network, but I can access the pods on each node.

If I do http://10.10.0.150:30935 (which is the node port I belive) I get a propper response form my webserver. But if I do https://10.10.0.240:30935 I just get a timeout…

Here are my services:

How did you changed the config file to Ignore fails. Can you please guide me the steps?
