Solutions

Set vhostHTTPPort in the frps configuration so HTTP proxies can be served.
Use a different proxy type (for example tcp) if the server has no vhost HTTP port.

When it happens

Trigger: Raised by validateProxyConfigForServer in pkg/config/v1/validation/proxy.go when an HTTP proxy is configured but vhostHTTPPort is not set on the server.

Common situations: A proxy of type http is declared while the server's vhostHTTPPort is 0/unset. Fix by setting vhostHTTPPort in the server config or using a tcp proxy instead.
