task - install rancher worker role

conditions - v2.6.2, rke2, k3s, (v1.21.6+k3s1), updated ubuntu 20.04, gre tunnel from local network to remote server, I have not tested it on a virtual machine from another provider, there is no such possibility yet, of course, I will check for linode or hetzner later. connection between lan and remote virtual server on cloud provider - gre tunnel(ping, tracerote shows all is ok with connection)

consequence - installing worker role hangs

cause - presumably network configuration, but …
