Create an EC2 instance with Ubuntu 18.04 (I used t3.nano), and ssh into it
sudo apt-get update
sudo apt-get upgrade
Install PiVPN with curl -L https://install.pivpn.io | bash
Follow the on screen instructions. Mostly use defaults but the protocol must be TCP, and I chose 1443 as my port
Install obfsproxy with pip install obfsproxy
Create a service file /etc/systemd/system/obfsproxy.service with contents

[Unit]
Description=Obfsproxy server

This was copied and pasted from here.

Many years ago, it was standard practice to store passwords in plaintext in databases. This was a bad idea because, when the database was compromised, the attacker got all the passwords. To combat this, we started hashing passwords in the database using one-way cryptographic hash algorithms. MD5 became popular, but weaknesses (collisions, partial preimage, etc) discovered in it mean it's no longer recommended. A lot of people moved onto SHA1, which is more secure.

The problem with this approach is that it's possible to construct a huge table of hashes and their corresponding plaintexts. These are called rainbow tables. They work on the concept that it is more efficient to compute a huge list of hashes for all possible passwords (within a certain set) and then store it, so it can be quickly queried later on. So, instead of brute-forcing indi

Start an AWS EC2 Instance from the Ubuntu 16.04 Amazon image. t3a.micro will do. Open ports 22 and 2443. Assign an elastic IP so it can't change.
Download the private key for the EC2 instance whilst creating it
SSH into the server
Update to the latest sudo apt-get update then sudo apt-get upgrade -y
Install PiVPN curl -L https://install.pivpn.io | bash. Make sure to select TCP and not UDP when given the option. Set the port as 1194. The rest can be left as defaults. If the screen does a strange flashy thing try ssh from Cygwin instead.
Install obfsproxy sudo apt-get install obfsproxy
Put the attached systemd file at /lib/systemd/system/obfsproxy.service
Start the service sudo systemctl enable obfsproxy then sudo systemctl start obfsproxy
Add users with pivpn add. Then follow the steps it gives you.
Use scp to download the .ovpn files and put them on relevant devices. You'll need to modify 1443 to 2443 as the port number in these client config files.

Go to chrome://net-internals/#hsts
Under Query HSTS/PKP domain type localhost and click query. If it says not found this is not the solution. If it lists some things, continue.
At the bottom, under Delete domain security policies enter localhost and click delete
Done!
