Unable to connect to VPN with IP, user and password

I was asked to connect to a VPN with only IP address, user name and password. It works perfectly fine in Windows by leaving everthing in automatic and settings IP, username and password. EDIT: I was then told it was PPTP. I solved it I detailed in the comments section

On Pop OS I try using the PPTP option in VPN settings, setting Gateway to the given IP, user and password in their field, and leaving NT Domain blank and everything as default. When I try to connect I get the meaningless push notification error saying I was unable to connect.

Do you know how to connect to a VPN in Pop? OpenVPN won’t let me create the connection without a CA certificate (that I don’t need because it worked on Windows 11, which I don’t want to work with at all)

It turns out the firewall on my machine was blocking everything, I feel stupid…

If you find yourself in this situation, try disabling the firewall with `sudo ufw disable` (just for the test!) and if it works do what this kind man says here.
