Handshake for peer did not complete: What is blocking my Wireguard connection to Surfshark?

I'm using a Surfshark VPN and want to connect to Surfshark via the Wireguard protocol. I have installed the Wireguard program, downloaded the configuration file from the Surfshark website with the keys generated by Surfshark. However, when i press 'Activate' it keeps initiating a handshake but never completes.

Things i have tried:

• Opening ports on windows firewall
• Googling
• Forwarding ports on router
• Changing settings in the config file

What am i missing?
