Troubleshooting
The Social Scheduler errors you are most likely to hit, what each one means, and how to clear it. Start here when a post shows a red error.
How to read this page
Each issue below follows the same format: what it means, and how to fix it. If a post shows a red error message, check here first — the error message shown in Nabu is written to be specific and actionable, not a raw technical code.
A post shows "Failed" with a message about updating an app
This is a TikTok-specific message telling you the TikTok app on the connected creator's phone is out of date. TikTok requires a recent app version to accept posts sent through Nabu.
How to fix it: Update the TikTok app on the phone signed into that TikTok account, then select Retry on the failed post.
A post shows "Failed" with a message about reconnecting a channel
The stored connection for that channel has expired or been revoked, usually because of a password change or a security review on the platform's side. Facebook and Instagram access expires roughly every two months by design.
How to fix it: Go to Schedule, open the Settings tab, and select Reconnect next to that account. Sign in again and approve the permissions, then retry the failed post. Don't disconnect first: that deletes the connection, and reconnecting keeps everything in place.
Connecting a channel fails right away, before you even get to approve anything
This usually means the specific permission Nabu requested for that platform isn't available yet. LinkedIn's Company Page permission is still pending review with the platform — see Connecting Channels for what's available today.
How to fix it: Nothing to do on your end — this resolves automatically once the pending platform review is approved.
A channel is stuck on "Waiting for first sync" with no analytics
See Analytics for why this happens per platform. In most cases it just means the first automatic sync hasn't run yet — try Sync insights manually.
I can't select certain post types for my upload
Post type options depend on what you uploaded. Story and Reel-style post types generally require a video or a single image — a multi-photo carousel won't offer every post type. Try re-selecting the channel after uploading the correct media type.
TikTok published, but nobody can see the post
Check the privacy setting on the post. TikTok posts carry their own privacy level, and one set to "Only me" publishes successfully while staying invisible to everyone else. You can see and change this per post in the composer, under the TikTok settings.
Worth knowing: if the TikTok account has comments, Duet, or Stitch disabled account-wide, that setting overrides whatever the post asked for. See the TikTok section in Connecting Channels.
"Keep uploads under 500 MB"
Your file is over the 500 MB limit — this is the same ceiling for both photos and videos.
How to fix it: Compress or trim the file and try again. If you're regularly hitting this limit, get in touch through Getting Help.
"Only image and video files are supported"
You selected a file type the Social Scheduler doesn't handle (a PDF or a document, for example). Only image and video files can be uploaded.
How to fix it: Select a photo or video file instead.
"Upload failed. Check your connection and try again."
The file didn't make it to storage — usually a dropped or interrupted internet connection partway through the upload, more likely on a large video or a slow network.
How to fix it: Select Retry, or re-select the file. Your caption, channels, and other settings already entered in the composer are not lost.
"Upload didn't complete. Try again."
The upload started but never fully finished before the composer checked on it.
How to fix it: Select the file again and re-upload. If this keeps happening on the same file, try a smaller export of it.
General questions
A post is stuck on "Publishing" — is something wrong? Publishing usually takes a few seconds to a couple of minutes. Video takes longest, because the platform has to download and process the file before it will accept the post. If a post sits on "Publishing" for more than 15 minutes, Nabu gives up on it and switches it to "Failed" with a message, so it never stays silently stuck. At that point you can retry it.
One thing to check before retrying a video post: open the channel and look for the post. Occasionally a post reaches the platform just as the publish is interrupted, so it goes live without Nabu hearing back. Retrying then would post it twice.
Where do I go if none of this resolves my issue? See Getting Help to open a support ticket. Include which channel and platform is affected, and the exact error message shown on the post.
