Can't connect to a server from linux machine (all other devices connecting perfectly)

[xorium]

When I click on "connect" seems like everything fine and after some seconds I've connected. But I can't resolve domains (host google.com failed by timeout), I can't ping everything including 9.9.9.9, seems like problem with tunnel creation.

My machine:

$> uname -a

For me, on Debian Unstable, it works well until I suspend the computer. Then, Outline client states it is connected, but all traffic goes directly to the internet. After disconnecting, it is necessary to disconnect and connect wifi again.

I'm happy to help troubleshooting. For now, using shadowsocks-libev as client.

A few things:

• You can't ping because Shadowsocks doesn't support ICMP
• The failed to store tunnel error is output here. cannot save invalid tunnel here. It seems like the config is somehow missing some piece of configuration, as it's failing the IsTunnelValid test.
• There seems to be an issue with the auto update. You may want to manually download the new version. We'll try to address with https://github.com/Jigsaw-Code/outline-client/issues/1240.
• It seems the Linux client can't recover properly from sleeping. We need to investigate that further.

Thanks for getting it at work.
