403 in my custom domain but 200 in .onrender domain

when I try to make a post request I get a 403 error from the domain lemon-py.com but when I do it from lemon-py.onrender.com the postis done and the status is 200.

Hi Gaston,

Could you provide any additional details about the problem you’re facing? Is there a flow I can go through on lemon-py.com that involves making a POST so I can reproduce the issue?

Regards,

Matt
