When parsing through a proxy, it gives a 404 page?

Question

PHP

Hello, I ran into a problem that when parsing a site page through a proxy, it often gives a 404 page and not a normal
one. If I turn off the proxy, then everything is parsed as it should.
Why is this and how to fix it?
I use the python standard function
r = requests.get( url , proxies = proxy_obj )
. Perhaps in other languages ​​​​someone also encountered this problem.

It all depends on the proxy and its type, here the video tells about this moment https://www.youtube.com/watch?v=EBfQa8NkJbA&list=P...
There were already questions with a similar problem somewhere, one the person gave quite practical advice: buy a cheap VPS and order a lot of IPs (as the answerer claimed, you can buy it for a penny). There was also an option to parse through Tor.
