VPN kindof loses internet connection

[langmeg43]

I am running Ubuntu 20.04 on a Virtual Private Server.
I downloaded OpenVPN using the following commands:

git clone https://github.com/Nyr/openvpn-install.git
cd openvpn-install && chmod +x openvpn-install.sh && ./openvpn-install.sh
./openvpn-install.sh

I also port forwarded to port 5555.

After doing this, I no longer have access to the general internet (Discord, or accessing any websites) when connected to the VPN however, I do have internet access as I can SSH into the root of my server via CMD on my Windows machine running Windows 10 & have access to the things I am hosting on the port or listening on the port.

In case this also helps, I port forwarded using the following commands:

iptables -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t INPUT -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t FORWARD -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t nat -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t nat -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t nat -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.xx
iptables-save
service ufw stop
iptables -t nat -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.xx
iptables-save
iptables -t nat -A PREROUTING -p tcp --dport 5555 -j DNAT --to 10.8.x.x
iptables -t nat -A PREROUTING -p tcp --dport 5555-j DNAT --to 10.8.x.xx

I dont have anything else installed on the Ubuntu server, it is a fresh install except for minor things such as git, apache2 and openvpn itself.
