Iphone not connecting to wireguard

Hello, I've recently setup a unifi wireguard vpn and I am trying to connect to it on my iOS , but is not liking it, it works fine on my pc though.

I get the message "Configuration reading or writing failed" with no further explanation. Has anyone seen that one before? I tried to restart my phone, I initially had 2 vpn configs from openvpn on my phone, but I removed the profile and openvpn app completely, just using wireguard now.

I also tried to disable Content & Privacy Restrictions with no luck :(
