This guide helps you resolve common Instagram connection problems and posting failures in Post Bridge.
Quick fix for most issues
The most common solution for Instagram posting errors is refreshing your connection. Go to the Accounts section and click Refresh Instagram. This re-establishes the connection and resolves most posting errors.
Video upload issues
If you're having trouble uploading videos to Instagram, follow these steps:
Navigate to the Accounts section of your dashboard
Click Refresh Instagram
Ensure the correct accounts, pages, and businesses are selected under Edit previous settings on the Meta reconnect page
Failed video posts from compression problems
If your Instagram video posts are failing due to compression issues, retrying the post will not resolve the issue because the retry uses the original, non-optimized video file.
To successfully post the video, you must remake the post and reupload the video so it is properly processed and compressed according to Instagram's standards.
Common error messages
Request failed with status code 400
If you see this error when posting to Instagram, go to the Accounts page and click the Refresh Instagram button.
400 Session Invalid errors
This error indicates a session issue on Instagram's side. You have two workarounds:
Wait 12 hours and try connecting again
Connect via Facebook Pages: Connect your Instagram account to a Facebook Page, then use the Facebook login for Instagram integration
OAuthException code 2
The error "IG Error (OAuthException, code 2): An unexpected error has occurred" suggests authentication problems due to backend issues.
"Already connected" or "Unsupported get request"
For these connection errors:
Deauthorize Post Bridge from your Instagram account at https://www.instagram.com/accounts/website_permissions/
Reconnect through Post Bridge
If "Unsupported get request" errors persist, they might be related to video codec issues that require patches.
Instagram account requirements
Your Instagram account must be set up as a Creator or Business account and linked to a Facebook Business Page to work with Post Bridge.
Alternative connection method
If direct Instagram connection fails, use the Facebook connection workaround:
Connect your Instagram account to your Facebook pages
Use the Facebook connection option in Post Bridge
This method works when direct Instagram connection fails
Advanced troubleshooting
For persistent connection issues, try the deauthorization process:
Remove Post Bridge from your authorized applications
Return to Post Bridge and reconnect your account
Most Instagram connection and posting issues can be resolved by refreshing your Instagram connection in the Accounts section. Try this first before attempting other troubleshooting steps.
