Hi Folks, I am attempting to set up and use a wireguard VPN on my YUNOhost (on a bought VPS).
I have installed it and I have been successfully able to use it from my Android phone, activated via the wireguard app. However on my Debian-based desktop, although it works the connection is extremely slow, sometimes drying up altogether. Might it be getting impeded by my firewall (ufw)? Or something else? I am not sure how to proceed.
Thanks in advance for any advice you can offer 🙂
