Instagram auto reply DM Problem

Describe the problem/error/question

Hi all,

I made instagram automation workflow in n8n.

So if people’s comment contain “keyword” in one spesific post, they will get automatic DM (only 1 time message, not for auto reply chat everytime people send message).

My problem is the workflow only run successfully if other person DM me first, but if they just commented on my post, the execution failed.

My bot can’t DM them first.

Any way to solve this issue?

I have bussiness verified for my apps and correct token.

What is the error message (if any)?

(only happened if the person commented in my post without DM me first):
Forbidden - perhaps check your credentials?
