Besides other answers - you could just use SSH port forwarding. Remote would be your home server, local would be your "cloud" server. You should initiate the connection from the cloud server to your home server. Playing with local ports would enable you filter what domains are used for the proxy.

I rarely use it, so the exact syntax is gone from my memory. It is a bit tricky at first, but definitely not rocket science to figure out.

Once the connection is established - you would point your scraper to https://localhost:localport
