I’m trying to reverse proxy a sub domain to my express website but when I’m trying the command

virtualmin create-proxy --domain
–path url-path
–url destination

Its returning error as-
Command was not found

Doc link- create-proxy – Virtualmin


Creating proxy paths is a feature (along side with many other) that is only available for Virtualmin Pro users.

is there any other way?

What other way?
