I bought a Pixel 6a a few days ago. Before I was using a Pixel 3a with GrapheneOS and Wiregurad.

Since Switching to the 6a I can connect to the wireguard server via a mobile network connection but my data is no longer routed through the VPN. So I have no Internet Access while using a mobile network. On my old Pixel 3a, however, the connection works fine with the same SIM card.

If I use a Wifi connection with my 6a, however, it works without any problems.

Double checked all the settings again, but since I restored them from a backup, the settings were the same.
I think this is a bug, but I'm not sure if it's from Android 13 or GrapehenOS.

    TheLynx changed the title to Issues to with wireguard over mobile network on a Pixle 6a .

    TheLynx Just before someone is comming up with it, no a reconnect does not solve the problem like descripted in reddit for example.

    I see why I didn't found it in the first place this is something more related to Android 13 and specific carrier setups.
    Turn off the "Block Connections without VPN" fixes the isseue with the connection but has privacy issues of cause.
    Strangely for me "Turing this off and on again" fixed the issue for me.
