Telegram Trigger node doesn't fire

I’m trying to connect my Telegram bot with n8n (hosted on Docker), and while the credentials are set up correctly and the bot is connected, the Telegram Trigger node doesn’t fire when I send a message to the bot. When I click “Execute Node” to test, it starts the workflow but then gives this error after a few seconds:

“Problem running workflow: The connection to the server was closed unexpectedly, perhaps it is offline.”

Is there something I’m missing? Do I need to expose any specific ports or run the bot and n8n on the same IP? Would really appreciate some help!

Hi,

Does it have the same behavior in all cases? Like when you simplify your workflow to just sending a simple message in reply? does that work?

Can you please share your workflow so we can better understand?
