Routing through where? If you put your proxy in the cloud then it definitely won't work as most providers block known cloud host IPs like AWS, Digital Ocean, etc. I placed my Raspberry Pi inside my home network so that when I'm traveling my traffic still appears to be coming from my home, which is what Spectrum and others are looking for to determine whether to show you the entire channel listing or just a small slice of available channels. If you're not showing a residential IP in their network then it doesn't matter what setup you use, it still won't work.
