# How to Resolve Instagram Connection Issues (Error 400)

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

2. Clear Cookies and Cache

* Open your browser settings
* Clear browsing data (cookies and cache)
* Restart the browser and retry the connection in OpusClip

3. 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

4. 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**
