A proxy server that passes your requests but strips out header data is sending one thing while a server expects another.
Most of the time, this doesn’t cause any issues; it just means the server thinks you’re located somewhere else and doesn’t have much data about you to report to analytics.
Errors come when a piece of software, a server, or a website expects one thing and gets something else.
It’s like opening a box labeled “puppies” and getting spiders. The more data the proxy passes, the fewer errors there are.
When you’re dealing with web proxies, you’re liable to encounter a wide range of possible errors.
