# Why do I get the "Social network returned an unknown error..." message on my Facebook posts?

If you see the error message: **"Social network returned an unknown error. Check the account to see if the post has been published",** this means that Facebook responded with an unexpected error while Publer was trying to publish your post.

### What does this error mean?

Publer was able to send the post to Facebook, but Facebook did not send back a confirmation. Because of this, Publer is unable to confirm whether the post was published or not.

###### There are a couple of reasons why this could happen:

1. A temporary issue on Facebook’s side.
2. Sudden changes in Facebook’s API that affect how Publer communicates with their platform.
3. Account-specific issues, such as expired sessions or [missing permissions](https://publer.com/help/en/article/how-to-fix-constant-reauthentication-and-permission-issues-with-facebook-instagram-1u0okfk/).
4. Connectivity or network interruptions during the publishing process.

### Here's what you can do:

* **Check your Facebook account** - Log in to your Facebook account directly and verify if the post was published.
* **If the post wasn't published** - Try publishing the post manually from Publer by clicking the "Publish" button, or [reschedule](https://publer.com/help/en/article/how-to-reschedule-posts-mypcso/) it for a later time.
* **Reauthorize your Facebook account** - To ensure a stable connection, [reauthorize](https://publer.com/help/en/article/how-to-reauthenticatereauthorize-social-accounts-on-publer-1hzx0kx/) your account on Publer. This refreshes the connection with Facebook and helps prevent similar issues in the future.
