Error connecting Instagram

If you try to connect your Instagram account to Metricool and receive technical error messages or authorization issues, this article will help you solve them.

Here you’ll find solutions to the most common errors related to OAuth, sessions, and verifications that may appear during the connection process.

General recommendations

To avoid technical errors when connecting Instagram:

• Use the connection through Facebook whenever possible: it’s more stable and has fewer technical issues
• Check your privacy settings on Instagram and Meta before trying to connect
• Clear previous authorizations if you’ve tried to connect several times without success
• If one connection method doesn’t work, try the other one (direct vs. Facebook)

➡️ Error: "400 Session Invalid"

This is one of the most common errors when using the direct Instagram connection (without Facebook).

The following URL appears with the message: https://www.instagram.com/oauth/authorize/third_party/error/?message=400%20Session%20Invalid

Why does it happen?

It’s a temporary Instagram API error, related to the OAuth authentication session.

Instagram can’t properly validate the session started in the browser during the authorization process with Metricool.

This error doesn’t depend on your Metricool account settings and is usually caused by:

• Expired or invalid Instagram sessions
• Browser cookies or cache
• Temporary issues on Instagram servers

Solutions

• Log out and log back into Instagram
• Clear cookies and cache or use incognito mode
• Wait and try again later
• Switch to the Facebook connection, which is more stable and reliable

➡️ Error: "Your future activity off Meta technologies is turned off"

The full error message is: OAuthException: "Your account's future activity history off Meta technologies is currently turned off. Please visit account center to change it."

Why does it happen?

A privacy setting in your Meta account is disabled, preventing external apps (like Metricool) from accessing your activity information.

Solution:

1. Go to the Meta Accounts Center: https://accountscenter.facebook.com/info_and_permissions
2. Click Your activity off Meta technologies
3. Select Manage future activity
4. Enable: Future activity
5. Go back to Metricool and try connecting your Instagram account again

➡️ Error: "Something went wrong, authorization could not be verified"

You receive a message indicating that the authorization failed or could not be verified during the connection process.

Why does this happen?

At Metricool, we don’t have specific details about the exact reason for the failure. This error can occur for two main reasons:

1️⃣ Authorization or verification conflicts (OAuth)

It can happen due to:

• Previous Metricool authorizations saved in Instagram.
• Browser cache or cookie issues.
• Temporary failures during the OAuth verification process.

Recommendation:

1. Remove Metricool from connected apps in Instagram:

• Open the Instagram app on your mobile device.
• Go to your profile → Menu (☰) → Settings and privacy
• Select Website permissions → Apps and websites
• Find Metricool in the list and remove it.

2. Clear your browser:

• Clear cache and cookies.
• Or try in incognito/private mode
• Or use a different browser.

3. Try connecting again from Metricool.

2️⃣ Restriction applied by Meta (API access)

This same error can also appear when Meta limits the account’s access to the Instagram Graph API (the official API Metricool uses to connect, publish, and retrieve data).

In some cases:

• No visible restrictions appear under Account Status.
• The account works normally inside the app.
• But access to external integrations is temporarily limited.

API access is subject to compliance with:

• Platform Terms: https://developers.facebook.com/terms
• Meta Community Standards: https://transparency.meta.com/policies/community-standards/

What you can do in this case

1. Check in Instagram: Settings → Account → Account Status.
2. Review whether you’ve received notifications or warnings.
3. If no visible restrictions appear, it may be an internal automatic review.
4. Make sure your account complies with Meta’s terms of use.
5. For more details, contact Meta Support.

If Meta restores API access, the connection can be completed successfully.

➡️ Error: Personal account instead of professional

You don’t receive a specific error message, but the connection doesn’t work or Instagram doesn’t appear as an option.

Why does it happen?

Metricool only works with professional Instagram accounts (Business or Creator). Personal accounts aren’t supported by the Instagram API.

Solution:

1. Open the Instagram app
2. Go to your profile → Menu (☰) → Settings and privacy
3. Select Account type and tools
4. Choose Switch to professional account
5. Complete the steps to become Business or Creator
6. Go back to Metricool and try connecting again
