Probably the channel_id you are using is not correct. Please, check this id belongs to the daemon user.

[DLX23]

Channel ID is the number after "C" and before "_" in Telegram Web URL?

[alfem]

No, it is not.

Check this: https://gist.github.com/mraaroncruz/e76d19f7d61d59419002db54030ebe35

You can also get your channel id programatically or simply add one of those "get my id" bots to the channel.
