Troubleshooting the “400 Session Invalid” Error When Connecting Instagram

Updated yesterday

Seeing a “400 Session Invalid” error when trying to connect your Instagram account to Joli? You're not alone — this is a known issue some users experience across Instagram’s partner apps.

While the issue originates on Instagram’s end, there are a few things you can try that have worked for others.


What’s Causing This?

This error usually means your login session with Instagram has expired or become invalid. While we can't fix it directly from our side, these quick steps may help get you back on track.


Try These Fixes

1. Refresh Your Session

  • Log out of Instagram completely

  • Close the browser or app

  • Reopen Joli and try connecting again

2. Clear Cookies and Cache

  • On your device, clear browsing data

  • Try the connection again through the Joli app

3. Switch Networks

  • Move from Wi-Fi to mobile data, or vice versa

  • A different network can sometimes bypass the session error


Still Stuck?

If nothing works right away, it may be a temporary hiccup on Instagram’s end. Waiting a bit and trying again later often does the trick.
