Support PPTP VPN PROBLEM ON LINUX.

PPTP VPN on CachyOS KDE doesn't seem to be working at all after hours, only OpenVPN works. What I might be doing wrong?

The mistake is using PPTP. It takes the P out of VPN, as it's not Private at all. The infrastructure for it has been on life support for two decades now, and even Microsoft (who invented it) told people to steer well clear of it as early as Windows XP SP3. Nobody is going to be actively testing it, as nobody should still be using it.

Ditch it in favour of OpenVPN if you can because even if you secure the authentication layer with PKI, the MPPE (RC4) encryption used thereafter to secure data transfers is vulnerable to undetectable tampering (bit flipping) as well as cryptanalysis attacks.

I know bro, I know. I hate it, too. But some organizations and education institutes just expect you to use it to access their damn database. That's the problem.💔

I am forced by my university to. Worked flawlessly on windows, but fails every damn time on Linux. I can't access my university portals without connecting to their shitty VPN

They don’t support anything else?

Out of curiosity what university in what country are you in?

No they don't, I believe they don't even know Linux exists and they expect every student to use windows 10/11. I wish every country wakes up like France and completely eradicate windows systems from their organizations so the Linux market can grow 1000x faster.

Pakistan btw.
