Something you may also try is the following:
using your telegram client (e.g. on your mobile phone)
/start to your bot
- send a random message such as
- check again using the URL
You will need to show me the exact URL you use to (I assume) retrieve the chatID from the bot if this doesn’t work
(As the token is sensitive information, perhaps it is best to send it in a private message). Likely there is an error in the URL (https://…) in this case, as all other users have been successful using this method as far as I know. This problem is not caused by Pimatic-Telegram as you are still in the prerequisite stage.
