Troubleshooting
Solutions to common issues you may encounter when using MultiPost.
Upload stuck at "Processing"
This usually indicates a network issue or a temporary platform API outage. Try the following: (1) Check your internet connection. (2) Refresh the dashboard page. (3) If the upload has been processing for over 30 minutes, try canceling and re-uploading. (4) Ensure your video file is not corrupted by testing playback locally.
OAuth connection expired / "Re-authorize required"
Social media platforms periodically expire OAuth tokens for security. Go to Settings → Connected Accounts and click "Reconnect" next to the affected platform. You'll be redirected to re-authorize MultiPost. This does not affect your existing uploads.
Video uploaded but not visible on the platform
Some platforms (especially YouTube) process uploaded videos for several minutes before they become publicly visible. Check the Activity page in MultiPost for the upload status. If the status shows "Success" but the video isn't visible after 1 hour, check the platform's native studio for any processing errors or policy violations.
Video rejected by platform
Each platform has content policies and technical requirements. Common reasons for rejection: (1) Video format not supported. (2) Video duration exceeds platform limits. (3) Content policy violation (copyright claim, community guidelines). (4) File size exceeds maximum. Check the error message in the Activity page for the specific reason.
Thumbnail not showing correctly
Ensure your thumbnail meets the platform's recommended dimensions: YouTube (1280×720), Facebook (1200×630), Instagram (1080×1080 or 1080×1350). Use JPG or PNG format under 2 MB. Thumbnails may take a few minutes to process on some platforms.
Scheduled post didn't publish
Check the following: (1) Your OAuth connection is still active for the target platform. (2) Your account has remaining daily upload quota. (3) The scheduled time hasn't passed while you were editing — confirm the time zone in Settings. (4) Check the Activity page for any error notifications.
Video quality appears degraded after upload
All social media platforms re-encode uploaded videos, which can reduce quality. To minimize quality loss: (1) Upload in the highest quality available. (2) Use MP4 with H.264 codec. (3) Set your bitrate to at least 10 Mbps for 1080p content. (4) Some platforms initially serve a lower-quality version and upgrade after processing is complete.
Cannot connect Instagram account
Instagram API integration requires a Professional (Business or Creator) account, not a personal account. To switch: open Instagram → Settings → Account → Switch to Professional Account. Also ensure your Instagram account is connected to a Facebook Page, as Instagram's API routes through Facebook.
