Consul - "No private IPv4 address found" error

"ubuntu 20.04"

I am trying to start Consul service with this command:
`/usr/bin/consul agent -server -ui -data-dir=/temp/consul -bootstrap-expect=1 -node=vault -bind=0.0.0.0 -config-dir=/etc/consul.d/`

it gives ==> “No private IPv4 address found”

I also find a page regarding same issue but since I am starter level at linux. I couldnt apply solution.
https://github.com/hashicorp/consul/issues/725

What is the issue?

Start with the reported Consul agent command on Ubuntu 20.04 and compare the “No private IPv4 address found” behavior with the referenced Consul issue #725. Confirm which network configuration causes the address lookup to fail and document a reproducible resolution for the stated command.
