Error 400 Session Invalid - How to solve??


Swedishalexa

Hey, this is the first time Im using Manychat. I tried to connect my Instagram account but the screen gets fully black with an error text “400 session invalid”. I tried to connect my instagram account both from a PC and mobile but I still get the same error.

 

Does anyone know how to solve it?

@Swedishalexa I'd start testing with a different browser or computer, or after cleaning cookies and history.

If after that you still have issues, I suggest you contact support.

Hi,
thank you for your reply. Unfortunately, it didn’t help – I’m still experiencing the same issue.
By the way, this is the only thing I can see in my Manychat account (see the screenshot).
