Hi Dario, Are you able to show us a screenshot of what the request that you are trying to send looks like?

Hi, don't know if it will help but I had the same problem when I was using HTTP/2. I unticked the "Default to HTTP/2 if the server supports it" setting and it worked. If someone knows why, feel free to explain. thanks
