[Bug]: Proxy Check not working, Proxies declared as not working

[swordo51]

Note: I did not censor the Proxies because they are avaible for free.
I also tried payed residential proxies and they did not work either.

Version of the software
0.3.2[beta]

Operating system
Windows 10 VM
No Firewall activated
No MS Defender

Browser / Native
Browser Client

What happened?
The Proxy Check is not working.
All the Proxies I add and try to check are giving the output not working, even though they work (tested with other checker).
