How to Fix the 400 Session Invalid Instagram Error in Instagram Agent

August 25, 2025

Jotform makes it easy to connect your Instagram account to an Instagram Agent, but sometimes you might get a 400 Session Invalid Instagram Error when connecting it. This usually shows up when your Instagram session has expired or something isn’t working right with the connection. The good news? It’s usually temporary, and you can get things back to normal by trying a few simple fixes.

Why This Error Happens

The 400 Session Invalid Instagram Error isn’t random—it usually means something’s off with your login or connection. Usually, it comes down to one of these common issues:

  • Expired Login Sessions — Your Instagram login has timed out.
  • Cache Conflicts — Old cookies or saved data are messing with the connection.
  • Security Checks — Instagram blocks the connection if it spots unusual activity.
  • Wrong Account Type — You’re trying to connect a Personal account instead of a Business or Creator account.
  • Connection Issues — Sometimes your network or device settings can mess with the login.

How to Fix It

Here are a few things you can try to fix the 400 Session Invalid Instagram error:

Clear the Cache or Use Incognito Mode 

Sometimes old data gets stuck and causes problems. Clear your browser’s cache and cookies, then try reconnecting. If you don’t want to clear everything, open a private/incognito window and log in from there. You can check out this guide on Browser Cache, Cookies, and Incognito Windows to learn more. 

Check Your Account Type

Make sure your Instagram is set up as a Business or Creator account—Personal accounts won’t connect properly. If you’re still using a Personal account, switch it in your Instagram settings. You may also need to link it to a Facebook Page for everything to sync smoothly. You’ll find more info in these guides on How to Set Up a Creator Account on Instagram and How to Set Up a Business Account on Instagram.

Verify Your Login Activity

Go to your Instagram login activity and check for any unusual or unknown sessions. If you see logins from places or devices you don’t recognize, remove them. Once everything looks clean, try reconnecting your account with Instagram Agent. For a quick how-to, check out this guide on View Your Account’s Recent Login Activity.

Update Your Password if Asked

Sometimes Instagram will ask you to reset your password for security reasons. If that happens, go ahead and update it right away. After resetting it, head back to Instagram Agent and reconnect your account with the new password. Need a hand? This guide on Change your Instagram Password is a great place to start.

Switch Networks

Your internet connection can sometimes be the problem. If you’re on Wi-Fi, try switching to mobile data, or if you’re on mobile data, connect through Wi-Fi. A fresh network often fixes session errors instantly.

Use Another Device or Browser

If nothing else works, change up the device or browser you’re using. Try logging in from your phone instead of your computer, or the other way around. You can also switch browsers—Chrome, Firefox, Safari, or Edge might give you a clean connection.

When to Contact Support

Most of the time, the 400 Session Invalid Instagram Error goes away after trying the fixes above. But if you’ve tried everything and it’s still not working, it might be time to get some extra help. Here’s what you can do:
