Why am I getting an unsuccessful social post error in HubSpot?

If a social post doesn't publish from HubSpot, the post will show an error explaining why. Below are the most common errors and how to fix them.

HubSpot's social publishing tool is available with Marketing Hub Professional and Enterprise.

Image rejected

The image doesn't meet the social network's requirements. To fix it:

  1. Check that the image meets the network's recommended file size and dimensions. See HubSpot's image size requirements for social posts.
  2. Make sure the file is a JPEG or PNG.
  3. If the image is linked from a URL, make sure the link still works.

Authorization failed

The social account is no longer connected to HubSpot. This often happens after a password change, a change in page admin access, or when the connection expires. To reconnect:

  1. In HubSpot, click the settings icon in the top navigation bar.
  2. In the left sidebar, go to Marketing > Social.
  3. Hover over the account and click Reconnect in the Status column.
  4. If the account has been disconnected for more than 90 days, it won't appear in the list. Click Connect accounts at the top right, then click Continue to reconnect it.

Tip for LinkedIn: the person reconnecting must be an admin of the LinkedIn Company Page.

Third-party network issue

The social network had a problem on its end. To fix it:

  1. Confirm the social account is still connected (see Authorization failed above).
  2. Check that the image or video meets the network's size requirements.
  3. Check the social page itself to make sure the post didn't go through anyway, so you don't publish a duplicate.
  4. Clone the post and publish the copy.

If it still fails, contact HubSpot Support or the Gate 39 team.

Facebook rate limit

Facebook limits how many posts and requests apps like HubSpot can send in a period of time. Wait up to 24 hours, then publish the post again. The limit resets automatically.

Bitly monthly limit

If your HubSpot account uses Bitly for short links, posts can fail once your Bitly account reaches its monthly limit. You can:

  • Upgrade your Bitly plan or wait for the limit to reset.
  • Disconnect Bitly to keep posting without custom short links: go to Settings > Marketing > Social, click the Publishing tab, scroll to Publish with custom short links and click Disconnect.

Posts publishing a few minutes early or late

If a post publishes within about 10 minutes of its scheduled time, it isn't an error. The Publish like a human setting is likely turned on, which varies the publishing time slightly. You can check it under Settings > Marketing > Social > Publishing.
