Why scheduled reels fail to post, and how to fix each error

Last checked against each platform's own docs

Why did my scheduled reel fail to post?

Check four things in this order: is the account still connected, does the video meet the platform's limits for length, format, frame rate and file size, was the daily posting cap reached, and did the prepared post expire before it was published? Then match your tool's error message in the table below.

Three quick checks first

  • Is the account still connected? An expired login stops every post. Reconnect the account in your tool.
  • Is your Instagram still a professional account? Publishing through the API needs one.
  • Did you hit a daily cap? Instagram, Facebook and TikTok all limit posts per 24 hours through their APIs.

How to stop it happening again

  1. Use one export preset

    MP4, H.264, AAC, 1080 × 1920, 30 fps. It fits the published reel limits of every major platform.

  2. Keep reels to 90 seconds if they go to Facebook

    Facebook Page reels published through Meta's API stop at 90 seconds.

  3. Check connections weekly

    Open your scheduler's accounts page once a week and reconnect anything that's flagged.

  4. Leave room under the caps

    Don't stack a day's posts at the limit, especially when several tools post to the same account.

  5. Watch the first post after a change

    After a new export setting or a reconnected account, make sure the next post goes live.

The easier way

  • Every post is checked against its platform's limits before you can approve it: caption length, hashtags, video length and carousel size. Anything that breaks a limit is flagged so it's fixed before it's scheduled.
  • Reels made in Socialhand are cut, captioned and sized for each platform.
  • If a platform still refuses a post, it's marked as failed with the platform's reason in your calendar, and the morning email says how many posts failed that week.
  • Plans start at $97 a month for all 8 platforms, and you can try it free first.

Questions people ask

Why did my reel post on Instagram but not on Facebook?

Check the length first. Facebook Page reels published through Meta's API can be at most 90 seconds, while Instagram Reels can run to 15 minutes.

Why does my scheduled TikTok only show to me?

TikTok makes everything posted by an app private until that app passes TikTok's audit. Check which tool posted it.

Do I have to upload again after an error?

Usually. A prepared Instagram post expires after 24 hours, so a failed or expired one has to be prepared again from the file.
