On UniFi networks running CyberSecure, web traffic to Wireguard.com for downloads will tend to get blocked. Here’s how to allowlist in UniFi Cybersecure (as of 5/7/26, Network Application 5.0.16)
To allowlist –
Go into Unifi Network Dashboard for the Site
> Settings
> Cybersecure
> Content Filters
> Applied Policy (Default or whatever it’s named)
> Allowlist
> add wireguard.com
> Save Changes
And then refresh the webpage on whichever device you’re connecting from.
Might need to then go into Incognito to load the download.wireguard.com/windows-clients webpage, but it’ll get you moving forward again if you need it 🙂 otherwise we should have a Wireguard MSI in our IT Software Archive in OneDrive.
