If you’re encountering a “400 Session Invalid” error when trying to connect your Instagram account to OpusClip, you’re likely dealing with a known session issue originating from Instagram. This commonly occurs when the login session has expired, been cached incorrectly, or was never fully initialized, especially with new or recently changed accounts. While the error is generated by Instagram itself (not OpusClip), we’ve compiled several reliable fixes that have worked for users facing this exact issue.

​
Troubleshooting Steps

  1. Refresh Your Instagram Session
  • Log out of Instagram across all browsers and mobile devices
  • Close the browser or app entirely
  • Log back into your Instagram account
  • Then return to OpusClip and try connecting again
  1. Clear Cookies and Cache
  • Open your browser settings
  • Clear browsing data (cookies and cache)
  • Restart the browser and retry the connection in OpusClip
  1. Try Another Device or Browser
  • Use a different browser (e.g., Chrome, Firefox, Safari)
  • Or switch between desktop and mobile to eliminate device-specific issues
  1. Switch Networks
  • Change from Wi-Fi to mobile data, or vice versa
  • Network-related session conflicts sometimes resolve with a new IP address

If Nothing Works Immediately…

This issue sometimes resolves itself after a short delay. If none of the fixes above work:
  • Wait about 1 hour (it should be a temporary issue)
  • Open OpusClip in incognito/private mode
