Hello, good day.
I have completed most parts of my project. The only remaining task is to implement a system that checks and validates my proxies, updates their status, and ensures that I do not distribute dead proxies to users.
Currently, I am using cPanel where I installed a Python script and set up a cron job. The cron job sends requests to my PHP script, which fetches the proxies and validates them. This setup was working well at first.
However, I discovered that the validation is only accurate for HTTP and HTTPS proxies. It is not reliable for SOCKS proxies because outbound connections are restricted on my cPanel hosting environment.
I am now considering getting a VPS to handle the proxy testing instead. I would appreciate your opinion on whether moving to a VPS is the right solution or if there is a better alternative.


Thank you.

best VPS option go for https://www.hetzner.com/cloud/ (you can consider arm64 VPS) 2x better performance.
 
Yes - VPS is the correct move.

Shared hosting/cPanel usually blocks outbound raw TCP, so SOCKS4/5 checks won’t be reliable. HTTP works because it’s just web requests, SOCKS needs real socket connections.

Get a small VPS and run proper TCP/SOCKS handshake checks with short timeouts and retry logic. It’s the simplest and most stable solution.
 
Yes, a VPS is the correct solution because shared cPanel hosting blocks outbound ports, making SOCKS proxy checks unreliable, while a VPS gives full network control for accurate testing.

In this case, switching to a VPS is a reasonable solution. Shared hosting like cPanel often restricts outbound connections (especially SOCKS), which makes proxy checking unstable. A VPS gives you full control over network configuration and ensures a more accurate authentication process
 
Yes, moving to a VPS makes sense. Shared hosting often blocks certain outbound connections, so SOCKS proxies just won’t be checked properly there. With a VPS you’ll have full control, and your tests should be much more accurate. It’s a cleaner and more stable setup for what you’re trying to do

VPS is the right move but don’t just copy the same cron + php flow there.

If you’re serious about not pushing dead socks, spin up a small VPS and run a dedicated checker service - pure python or go - async sockets, real SOCKS4/5 handshake, test against multiple endpoints not just one URL. I usually test TCP connect + external IP echo + optional target like google.com:443 to confirm tunnel actually works.

Also separate "alive" from "usable" - some proxies connect but timeout under load. Track latency + failure rate over last X checks and auto downgrade before they fully die. Once you have that, expose status via internal API and let your panel pull from that instead of running checks inline. Cleaner pipeline + no more shared hosting bottlenecks.
 
trueplayer's point about not replicating the cron+php flow to VPS is the right call. while you're at it, also consider running a dedicated SOCKS5 checker like ProxyBroker2 or a simple asyncio script rather than relying on cPanel or shared hosting for outbound TCP checks.

shared hosting firewalls kill SOCKS4/5 validation but let HTTP through which skews your results badly. VPS + a lightweight checker you control is the cleanest way to get accurate liveness data on your pool.
 
My Python proxy checker script and cron job had an outbound restriction, but to fix that, I used a cPanel VPS from DedicatedCore. So now I have HTTP, HTTPS, and Socks validation on the same server working smoothly, updates status accurately, and I no longer send dead proxies to users.
