No internet connection (P7 Pro / Chromecast with Google TV)

[sgzmd]

Hey folks,

I have a problem which I cannot make a head or tails of. I run the app on Chromecast with Google TV (v1, 1080p version, Sabrina) as well as Pixel 7 Pro. I have two different servers - one running in my home network, one in Linode. Both servers are working fine with Outline client (on the phone, it doesn't really work on the TV) - this is how I know that the server itself is functioning.

I use the following format for SS configuration:

{
    "server":"my.host.name",
    "server_port":30126,
    "local_port":1080,
    "password":"my-password",
    "method":"chacha20-ietf-poly1305",
    "remarks": "Outline Server"
}

There's only one remotely exciting thing in the logcat.txt, as per below:

I am attaching a snippet of logcat just in case though. The behaviour on P7 Pro appears to be near-identical.

Upon connecting the VPN, all connectivity just dies. Doesn't seem to be DNS issue (I hope, despite some murky messages in the log):
