Hi Everyone. i am running a ubuntu server version 20. Installerd node-red. The GUI is working en flows created. however im not able to create a websocket for instance with the samsung tv module. it gives me the error below:
27 Aug 17:02:09 - [info] Starting flows 27 Aug 17:02:09 - [info] Started flows 27 Aug 17:08:44 - [red] Uncaught Exception: 27 Aug 17:08:44 - Error: Error send Key at /home/user/.node-red/node\_modules/samsung-tv-control/lib/samsung.js:55:23 at WebSocket.

However when i run it from a windows machine the websocket is succesfully created.

Hi, this was [asked and answered in github issues](https://github.com/node-red/node-red/issues/3125#issuecomment-907458646) but to save anyone else looking into this...
The error is coming from a `samsung-tv-control` node.
My guess is the VM cannot reach your TV (network setup issue) and is crashing node-red. This is an issue with that node not correctly catching this error and you should raise an issue on the repository for the author to fix.
