CHATGPT connecting to N8N and it wont connect via POST

on the chatgpt side it it says that the POST isn’t active on the n8n side (which its), I have the correct URL implemented in both chatgpt and n8n, anyone have other ideas ?

What is the error message (if any)?

error POST

Did you use GPTs or just in normal prompt?

I only test the Custom GPTs that can use action to post data to my n8n.

can’t you use get? not tested with post, and if u do need post how are you calling the endpoint? You mentioned chatgpt? Could u explain more plz

I also tried to create a GPTs, (custom gpts)
I create an action to connect GPTs with a webhook in N8N installed in hostinger but it say "not able to reach webhook)
If I try curl command it suxceed,
If I try to connect N8N on Cloud it suxceed.
hostinger not.
