Hi there,

The response from the Telegram server means something is not correctly set up on the API. Could you please recheck the settings?

If everything is correct, could you please share a screenshot of the Telegam Settings in the Notification Template? Thanks.

With kind regards,

I'm pretty sure you've run into what you're using in the placeholder %device notification template. Use the %server synonym instead and the notifications will work. I recently encountered this myself.
