Hi everyone,

I am trying to send a message from MT5 to Telegram using a bot. However, I could not send the message from MT5 to Telegram due to the error:

'Error Code 400 Description "Bad request: chat not found"

Has anyone encountered the same problem? Can you give some reasons why this error might have occurred?

I did a lot of research online, but I could not get the right answers.

I have just got the same error" Error Code 400 Description "Bad request: chat not found" but everything worked perfectly before. I also did some research & havent found any solution.

Could anyone shed me some light how to fix this problem? Thanks

  {
//--- set token
   bot.Token(InpToken);

        // send msg
        int res=bot.SendMessage(InpChannelName,msg);

in my case, I just read old posts & know that im trying to send msg to a private channel. So I have just replaced the channel name with chat id & its working perfectly!

Thanks Andriy & other pro coders <3

Canyou explain how I can read messages from my own telegram channel? There is a bot connected as an admin to this channel, but the text of the message can not pull out. Would you be kind enough to give me a hint?

Hello, everybody.

Start of this week the file Telegram.mqh is giving some issues with the functions "ArrayAdd" and "WebRequest".

Is someone also facing this problems? I tried adding back the original files, but they seem to have the same issue as well.

Thank you and best regards,

Henrique
