Start with the exact destination outcome shown in Omni Writes. A multi-channel publish can succeed on one network and fail on another.
Connection problems
Reconnect the affected channel from Settings → Channels, confirm the username or Page, then retry only the failed item.
Check the destination’s channel guide for count, format, size, duration, aspect ratio, and mixing rules. Re-upload media that is private, expired, or no longer available.
Scheduling problems
Confirm the future time and timezone, then review the item in Calendar. Scheduled and published are different statuses: a queued item can still fail later during delivery.
Before retrying
Repeatedly retrying unchanged invalid media or expired authorization usually produces the same failure.
