Look, Twitter won’t allow to cast same tweet every time. As you are posting scheduled tweets I think, the tweet that you have tweeted once matches the tweet that your program is trying to tweet! That’s why it’s showing 403 “status is a duplicate” error. This happens most of the time this error occurs when you try to tweet from a file. So, here’s what you can do (what seems to be the solution I think),
- You can delete the same tweet from your twitter timeline.
- You can change the line of the tweet from your file.
Note: If you are not tweeting form a file or something like that, let me know. Also let me know if this works.
Hope it helps. I’ll look forward to your reply.
