so, I have tried all kinds of VPN possible in the App Store, and the only one that used to work was X-VPN but now it just says it cannot connect anymore.
my school blocks most of the websites and social media apps like Snapchat, Instagram, etc.
is there a way Jailbreak can facilitate the bypass?
thanks
Nothing you can do with Jailbreaking. You just need a good VPN.
Jailbreak won’t help you. If you’re good with computers you can make your own VPN using OpenVPN to connect to your house over port 443 or 80 which can’t be blocked by your school (if they blocked it they’d have to block all internet traffic). You can also get an Amazon Web Services or Google Cloud Platform trial account and set up your own VPN. It’s a little complicated, but if you’re good with linux and computers is a breeze. Here’s a link to how to get it running once you have an instance/computer running: How To Set Up an OpenVPN Server on Ubuntu 18.04 | DigitalOcean
Most school networks use basic web filtering and proxying and port blocking for both lan and wifi. There’s a pretty good chance all you need to do is find a VPN provider that hosts on port 443 (many do) and connect using IP instead of hostname.

Get a raspberry pi and make your own vpn
Psiphon was the only one that worked for me when I was in high school. Others wouldn’t connect.
i use a DigitalOcean box ($5 / mth) and run Pritunl (openvpn with web gui) over 443/TCP to bypass the filter.
Try using the EPIC browser which has a built in VPN or Opera on your computer. I have not encountered any “blocks” using those browsers
I use SkyVPN and it works
Windscribe and ExpressVPN are good vpns. They might actually solve your problems
Back in my day you had to bypass it with a county school board vpn (some tech savvy employees may know what it is in your case) and you had to input the proxy into the schools WiFi settings on your phone. Keep at it, you’ll get it 
Try VPN, before I used X-VPN (like you did) until the connection problems started.
Try Psiphon VPN also try downloading the VPN to a USB stick and taking it with you
Get VPN Proxy Master it works very well for me and it’s simple and free.
Most simple way is to get a private internet access VPN, if I remember correctly when I used to use them they offered a selection of ports to connect through including port 80 which is impossible for your school to block.
Kaspersky VPN is good.
Wrong sub
Edit: You chickenheads can get mad and downvote all you want, but it’s the wrong sub 
This isn’t an IT forum for script kiddies. It’s a jailbreak sub.
This… i use PIA VPN at work to bypass blocks
got a PC w/ Linux here, gonna try it
also, I was thinking about creating a server on my PC and an app that would automatically connect to my server (just like another VPN app) because some of my friends really need the bypass… would that be viable?
At my last high school I could see everyone in AD and reset passwords lol
