Sir i have checked my telrgram_bolt_id and telegram_chat_id twice they are correct still facing this ERROR.

@dhakadneeraj786 Sir,
I was getting the same error even after providing correct bot details.
but i read somewhere on the bolt forum that this might be caused due to incorrect generation of telegram bot id due to connectivity issues.
i rectified this error by deleting my previous telegram bot and creating a new one.
the new bot id was successful and the error was gone.
hope this helps,

Hi @dhakadneeraj786,

Check the last message of this thread Telegram error: Always show unauthorized

Sir I created a new channel and bot but still i am getting this ERROR.

Hi @dhakadneeraj786

I have also received this error at first. It was due to the typo mistake of 0(zero) instead of O(letter O or vice versa. Better try to copy-paste the id’s.

Hope this helps…
