I am having the similar issue. The only different is I have the firewall iptables enable.
When I disable the firewall everything is working.
However I would like to have the firewall enable and let multipass to work.
Do you know what are the ports that I need to enable so that multipass could work?
I am using edge version.
Below are some errors I manage to find:

Thanks in advance.
