Hi @Steve-Mcl ,

Already try as per your suggestion. it still the cast status node is play but have no any sound in speaker. and few minutes came `error load media`

but can play `test.mp3` by accessing [https://x.x.x.x:1880/endpoint/audio](https://x.x.x.x:1880/endpoint/audio) for now

So i think you are mixing up a few things. for example, your inject is sending a `https` URL and an endpoint of `node-red:1880/audio/test.mp3` but your endpoint is clearly `node-red:1880/endpoint/audio` etc.

For the sake of getting this resolved, I'll jump ahead to the final solution.

follow the COMMENTS and adjust the names to suit.

```

1. remove or disable other endpoints
2. Import flow
3. Read every comment & action them
  1. Update the base path in the "Set base path" function
  2. Update the inject nodes to match your PC IP and CAST IP

Already follow your step but still can not casting. The cast status node is play but have no any sound in speaker. and few minutes came `error load media`

How to make this not mixing up? Already try to change the file in node like below, it still works auto download `test.mp3` if try access `https://x.x.x.x:1880/endpoint/audio/test.mp3` in a browser

@mbonani Any advise about this?

RE: Mix-ups

1. Your screenshot does not match your flow export  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/c/8/c84cf0851fd176d9192beced26b247318ea57411.png)

2. I gave you a 100% working example, with multiple re-use (will support multiple MP3s without a single modification) and I provided instructions - but you are still posting the NON working flow!

Did you even try the working flow I gave you?

Hi @Steve-Mcl

> [@Steve-Mcl](#):

> Your screenshot does not match your flow export

I don't know why not match. because check the http in node url is `/audio` but the display node always have `[get] /endpoint/audio`

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/2/e25964fb7fdd7d7fc362592aefb68c355000a608.png)

I'm sorry and forget to posting your example with update from me. Let you know the flow with modification as per your instruction below.

As you can see why the display node (red box highlighted) change automatically to `[get] /endpoint/audio/:filename`

It imports normally on my node-red.

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/2/129acc7cbda3b51c61e4d4d60661d806d851d7b4.png)

What version is your node-red?

Try this...

1. remove every HTTP endpoint you have on your flows.
2. restart node-red
3. refresh your browser
4. Import flow
5. Read every comment & action them
  1. Update the base path in the "Set base path" function
  2. Update the inject nodes to match your PC IP and CAST IP

Ah, this must be a HA thing (doesnt occur in a default node-red install)

@mrrobot the demo i gave you should work if you update the INJECT nodes to include `/endpoint/`

Hi @mbonani, Well noted, understood now.

Already check the configuration have no any set credentials set here but still can't cast. Any missed a HA thing again?

The cast status node is play but have no any sound in speaker. and few minutes came `error load media`

Hi @Steve-Mcl already try update inject nodes to include `/endpoint/` but still can not cast.

Does the link work in a browser?

More importantly, does the link work in a browser on a different computer or smartphone?

Can you share your flow as it is right now.

Hi @Steve-Mcl,

Yes I can play this url `https://x.x.x.x:1880/endpoint/audio/test.mp3` directly to browser on different computer and smartphone. Only do add type header in the HTTP response.

I think no issue to play `.mp3` file now but why still can not cast ?

Let you know the flow as right now below

Does the cast node still work? There is a message in its README that states the following.

> Because I no longer use this node myself, there is unfortunately only limited support.

And, since you are running it on HA, I'd suggest that you use its media\_source integration for casting media. I posted an example above in [#3](https://discourse.nodered.org/t/how-to-cast-mp3-local-file-in-nodered-as-ha-addons/59607/3). If you have any questions regarding that, you can post on the [HA Forum](https://community.home-assistant.io/), they even have a [Node-RED category](https://community.home-assistant.io/c/third-party/node-red/31) there.

It works for me (non docker / non container)

  

@mrrobot I tested the flow you posted back & it definitely works for me.  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/1/41a38f86cbbb4cbfff3aac17c42452133982ef8f.png)

I suggest there is some other issue with your cast device or network (docker networking, host firewall?).

- Can you PING the cast device from node-red? (use node-red-node-ping to test this as it will ping from within the container)

- When you click the 🔍 button in the nodes editor, does it list your cast device?
