SVP webhook test returns error -1 on all URLs – how to debug request?

Hi, I am integrating SVP into an HTPC system using MPV with Ryzen 7 5700G and Vega iGPU hardware configuration. After the latest SVP update, I get error -1: Unknown error when testing webhook URL, even after trying many different addresses. I suspect the issue is related to HTTPS handshake or internal API changes. Has anyone dealt with a similar error or knows how to debug SVP webhook request details? Also, is it possible to configure SVP to send more detailed webhook logs? Thanks in advance! Geometry Vibes
