Webhooks

[On1kmc]

Hello!
I want to receive a webhook when the generation is complete. I specify my webhook in the request body.

webhook = 'https://my.server.ip.here:8443/replicate/photoresult';
String[] webhook_events_filter = {'completed'};

But I don't receive anything at the hook address.

i tryed send post-request on my address with body using postman, it's worked correctly.
Please, help)

upd:
I find this error:
encountered ssl error while making request: SSL:0A000086 certificate verify failed

I'm use self-signed sertificate, it's a problem?
