Good afternoon, I followed this tutorial:
Http://wiki.mikrotik.com/wiki/Manual:The_Dude_v6/Dude_Telegram_Example

But it is not working properly.
When I run a command line, no new RouterBoard New Terminal the command works perfectly and sends me a message.
When executing the test by Dude, the same does not send a message.

Did someone have the same problem?
