I use cloudflare for DNS.  Run the Ubuntu servers locally on a VMWare server 6.5.  Tried on Ubuntu 20.04 and 21.04 both not working.  Is this for an older version of Ubuntu maybe?

I get the following error when attempting to do a docker-compose up

ERROR: Service "caddy" uses an undefined network "web-proxy"

I tried adding it manually and it still fails.  I tried pasting this into portainer and it also complains about the networks.
