Triple Nested Directives

[samyules]

I'm trying to reverse proxy Netbird. It requires gRPC streaming to the backend on port 443. I need to set this global option to allow gRPC to port 443:

{
  servers {
    protocol {
      allow_h2c
    }
  }
}

I cannot figure out how use labels that will parse correctly. I tried caddy.servers.protocol: allow_h2c, but that produces:

{
  servers {
    protocol allow_h2c
  }
}

I also attempted caddy.servers.protocol.allow_h2c: but that resulted in an error. I cannot find any examples in the README that would produce a triple nested directive. Without this directive set, caddy gives the following error:

parsing upstream 'h2c://netbird-management:443': upstream address has conflicting scheme (h2c://) and port (:443, the HTTPS port), at Caddyfile

allow_h2c is no longer valid anyway. See the docs: https://caddyserver.com/docs/caddyfile/options#protocols

{
	servers {
		protocols h1 h2c
	}
}

So this should work: caddy.servers.protocols: "h1 h2c"
