- Remove the media file from your tweet.
- Try posting a text-based based tweet.
- Hit the Start button to proceed with the pass a Google reCAPTCHA challenge.
- Check the empty box.
- Hit the Continue button.
- Select Continue to X.

If you are getting the error while posting a tweet with media files, remove the media file/s from your tweet and try posting a text-based tweet only.

You’ll be prompted to take a moment to complete the security check. Hit the Start button under Take a moment to help keep X Safe screen. When you tap start, Google may collect and use information about you, your device and browser.

When directed to the Are you a robot screen, check the empty box under it and hit the Continue button to proceed further.

What is a Retweet?
A Retweet is a re-posting of a Tweet i.e., copy-pasting. It helps you and others quickly share that Tweet with all of your followers. You can Retweet your own Tweets or Tweets from someone else. Sometimes X users type “RT” at the beginning of a Tweet to indicate that they are re-posting someone else’s content.
