Certificate error exposing dashboard

i’m trying to start a microk8s instance on a LXD machine, following this docs (https://microk8s.io/docs/install-lxd), every thing seems working fine.

When i try to expose the dashboard service via microk8s dashboard-proxy i receive the error:

error: error upgrading connection: error dialing backend: tls: failed to verify certificate: x509: certificate is valid for, not

where is the ip address of my LXD container.

I tried to add all the IP address in the csr.conf.template file and to restart microk8s, also tried to execute sudo microk8s refresh-certs --cert ca.crt and sudo microk8s refresh-certs --cert server.crt as found in other topics but nothing changes.

Any insight is appreciated!
