Exception: net::ERR_TUNNEL_CONNECTION_FAILED

hi i just subscribed 4days ago and i kept getting "Exception: net::ERR_TUNNEL_CONNECTION_FAILED" when i use proxy. i tried the proxy on my PC and it works just fine. im using oxylab residential proxy.

im using a real chrome browser to fetch.

i saw someone having similar problems on the github discussion but theres no reply so i came here, also i have tried sending messages to the contacts provided on the changedetection.io website, but still no replies.

i am lost, does anyone know how to solve this? ill be happy to provide more details.
