Hi, thanks for the awesome plugin.
Unfortunately it recently also stopped working for me with the same error message: "Failed to connect to ws://ip:8123/api/websocket" where ip is my internal ip. I can reach the webinterface in Firefox from the same machine. I restarted mac/elgato, tried to create a new token, etc. So far no luck getting the plugin to work again.
Because i have no idea of this i also tried opening the websocket in firefox to test general connection, which returns:
No WebSocket UPGRADE hdr: None
Can "Upgrade" only to "WebSocket".

I run on Mac/latest OS (Sequoia).
As the error message in the plugin is quite limited i dont know where to search for errors or debug this. Let me know if you have any directions :-)

Hi,

there is a way to get more detailed logs. On MacOS it should work like this (can not test, because i do not own a mac device):

1. Run the following command in the terminal. It enables debugging of the stream-deck application:
   defaults write com.elgato.StreamDeck html_remote_debugging_enabled -bool YES
2. Restart stream-deck application
3. Point your browser to http://localhost:23654/
   
4. Select "PI" or "Plugin" to debug either Settings or the plugin itself. There, you have access to all log output and network activity:
   

PS. It seems that elgato has improved their Plugin API. When I find the time to migrate my plugin, it should be much easier to debug...

In the debug console I see:

WebSocket connection to 'ws://<my_ha_ip>:8123/api/websocket' failed: Error in connection establishment: net::ERR_ADDRESS_UNREACHABLE

From the command line on my Mac:

I see the exact same problem on my machine. If I use wscat, it outputs this:

Connected (press CTRL+C to quit)
< {"type":"auth_required","ha_version":"2024.11.3"}

The connection itself works, but not with the streamdeck plugin.

I tracked this down to what appears to be a change in recent OS X security settings. On my system, Elgato Stream Deck was disallowed access to the local network, see System Settings > Privacy and Security > Local Network. Once I enabled it, the plugin works again.

Awesome, thanks for your efforts @zerowidth

Awesome, that worked for me. Thanks @zerowidth

Brilliant ! Many thanks @zerowidth, it was simple but I didn't think about it.
