Wireguard not authorized (?)

Hi there

I managed to install the Wireguard-App via APK on to my Murena two.
I managed to setup the Server on my omv-NAS and scanned the QR-Code. So the Tunnel should theoretically work …?

However, when i try to switch it on in the Wireguard-App, it allways throws up the Message: “VPN-Dienst nicht vom Benutzer autorisiert” → “VPN service not authorized by the user”

What did i miss? What did i do wrong?

Im really thankfull for any help!

Regain your privacy! Adopt /e/OS the deGoogled mobile OS and online servicesphone

any other vpn already active? https://old.reddit.com/r/WireGuard/comments/zued0t/android_error_vpn_service_not_authorized_by_user/

After some re-installations, this seemed to be the problem.

Thanks a lot!
