Will Wahlu try again by itself?

Yes, when the problem is short-lived, like a busy network. History then shows Retrying automatically soon. For other problems, fix the cause and schedule the post again.

Where do I see the full reason?

The Publishing problems notification has the network's own reason. Your Overview page also lists recent failed posts under Needs attention.

Updated 7 October 2026

When a post fails, Wahlu tells you why. You see it in History, on your Overview page and in a notification.

Find out why

Open your brand and click History.
Pick the Failed filter.
Read the reason on the post. It says what to do, such as confirming your email in Bluesky. Then use the button next to it.

What the reason means

History says	What to do
Reconnect the account	The link to the account stopped working. Reconnect it.
Rejected the media or post details	The photo, video or caption broke a rule. Fix it in the calendar, then schedule it again.
Review the connection permissions	Wahlu is missing a permission. Reconnect and allow everything it asks for.
Could not complete this publication. Try again later	The network had a short problem. Wahlu often tries again by itself.
Blocked because of a policy restriction	Facebook blocked the post. See Fix Facebook Page problems.
A problem on our side, and our team has been alerted	It's our fault, and we already know. Check the network to see if it went out. If it didn't, post it again.
Wahlu could not prepare this publication	Something went wrong on our side. Contact us.

A post can also say Action required. That means Wahlu checked it before it went out and found a problem. For example, its photo was deleted, or it no longer meets the network's rules. Edit it in the calendar, then schedule it again.

Not a Business or Creator account. Switch your account type in the Instagram app. Then reconnect.
