I have a bot that can connect to chat, and send messages, but not get anything from chat. Does anyone know why not? I’ve tried on my channel and on another, more active one but… nothing.

Output and VB .Net console app code below:

Output

```
< PASS oauth:TOKEN_GOES_HERE
< NICK pilchard123
< USER pilchard123 8 * :pilchard123
> :tmi.twitch.tv 001 pilchard123 :Welcome, GLHF!
> :tmi.twitch.tv 002 pilchard123 :Your host is tmi.twitch.tv
> :tmi.twitch.tv 003 pilchard123 :This server is rather new
> :tmi.twitch.tv 004 pilchard123 :-
> :tmi.twitch.tv 375 pilchard123 :-
> :tmi.twitch.tv 372 pilchard123 :You are in a maze of twisty passages, all alike.
> :tmi.twitch.tv 376 pilchard123 :>
< JOIN #pilchard123

Sorry I don’t really know the programming language, but be careful about posting oauth tokens publicly (in your log output), they need to be kept private. I suggest you revoke access to that immediately if it’s valid.

And I was so careful to remove it from the code as well…

Thanks for the heads up!

When you send are you doing

```
PRIVMSG #room words to send

```

Syntax above wrong as on mobile. But I see no PRIVMSG in your code

Yeah, I use PRIVMSG to send. That works okay; the message shows up fine on the website. I just included the minimum code to reproduce the behaviour.

Or lack of it, as the case may be.
