Manual set of flatbuffer forwarding target is unavailable

[bvasiliev]

• I confirm that this is an issue rather than a question.

Bug report

It is no longer possible to manually set IP of an flatbuffer forwarding destination without mDNS or SSDP.

Steps to reproduce

Run hyperion 2.0.15 or above without ENABLE_MDNS option.

Try to enter IP address in flatbuffer forwarding target in web interface path Network Services > Forwarder > Activate

What is expected?

Available manualy set up hosts and ports for an json and flatbuffer targets, as it works before 2.0.13 release.

What is actually happening?

Error message "Discovery of service type [flatbuffer] via ssdp not supported" occurs.
The hosts and ports parameters fields are still not editable manually.

Forwarding option is unusable without ENABLE_MDNS.

As a workaround you can export the configuration, update the forwarder target server with its IP address and then import the config again.
The forwarder process will then use the IP to connect to the remote system.
I am currently at my mobile, but can share the json section to change when being at my PC.

Workaround with export-edit-import works, thanks!

Modified config section:

	"forwarder": {
		"enable": true,
		"flatbuffer": [
			{
				"host": "192.168.0.2",
				"name": "HyperBian",
				"port": 19400
			}
		],
		"flatbufferselect": [
			"192.168.0.2"
		],
		"jsonapi": [
			{
				"host": "192.168.0.2",
				"name": "HyperBian",

			}
		],
		"jsonapiselect": [
			"192.168.0.2"
		]

Good to hear it is working.
Just for completeness, you can also use an DNS-Hostname or an ipv6 address instead of the ipv4 one.
