I have working url to mp3, and I am trying to send audio to Telegram by this url. It works from time to time, but most of time it gives error
"A request to the Telegram API was unsuccessful. The server returned HTTP 400
Bad Request. Response body:
[b'{"ok":false,"error_code":400,"description":"Bad Request: failed to get HTTP
URL content"}']"
And I can't understand why, because I've checked the size and type, everything is clear, I can't find no more limitations in documentation of Telegram API. Who knows what is the reason of error?
