Known issues

This page collects the known issues for every network in one place. Each network has its own page with the details, for example X or Instagram. For fixes, see Troubleshooting.

#General

• Retries. When a network has a temporary problem (it can't be reached, it rate-limits you, it returns a server error, or media processing takes too long), Postline tries again. It tries up to 3 times in total, waiting about 1 minute and then 2 minutes. Other errors fail right away.
• Threads and comments. If a thread stops halfway, a retry continues where it stopped. Parts that already went out aren't posted again.
• Token refresh. Before publishing, Postline refreshes a channel's access token if it expires within 5 minutes. If the refresh fails, the post fails with "The connection to {channel} expired. Reconnect the channel." and the channel is marked as needing a reconnect.
• Revoked access. If a network rejects the channel's sign-in, the channel is marked "Reconnect needed". Owners and admins get a notification in the app and by email. Posts to that channel can't go out until you reconnect it.
• Failure notices. When a post fails, the person who created it and the workspace's owners and admins get a notification, in the app and by email.
• Public media. Facebook, Instagram, Threads, TikTok photo posts, Pinterest, Google Business Profile, Nostr, Farcaster, Slack and the blog networks fetch or link media from its public URL. On a self-hosted server, APP_URL/uploads/... (or your S3 public URL) must be reachable from the internet.
• Analytics. Postline refreshes engagement numbers for posts published in the last 30 days. Paused channels and channels that need reconnecting are skipped.
• Plugs. Auto-repost and follow-up are included in paid plans. Each plug runs once per post, when the post reaches the number of likes you set (50 by default). Only posts from the last 7 days are checked.
• Removing a channel. The channel is removed from posts that haven't gone out yet. Posts left with no channels are deleted.
• Self-hosters: encryption key. Changing ENCRYPTION_KEY disconnects every channel.
