Istio EnvoyFilter Lua HttpCall doesn't work with HTTPS?

I need to decrypt the body of a request in an external API.But, when I try to do it with an EnvoyFilter using lua it doesn't work.If I try the same code that I'm posting here, but without HTTPS, works. But with HTTPS returns 503.

The response error is:

503responseBody ->upstream connect error or disconnect/reset before headers. reset reason: connection termination

I'm using Istio v.1.11.4.
