Outline-client: Shows "Connected" after sleep, but really it's not connected

[OneHappyForever]

Describe the bug
The VPN still shows as connected after waking from sleep even though there is no connection. I need to manually disconnect and reconnect for it to work again.

The issue is that it shows up as "connected" while it's not connected.

To Reproduce
Steps to reproduce the behavior:

1. Connect to server
2. Wait for computer to sleep
3. Wake computer from sleep
4. NO INTERNET CONNECTION (need to disconnect and reconnect)

Expected behavior
Either:

1. The vpn works/reconnects automatically and successfully
2. Show the VPN as disconnected and give me a normal internet connection (at this time I can't access the web at all)

Same issue here. And this issue also happens randomly without sleep. Outline is very unstable on Linux.

Version: Linux v1.0.10

Hi all, thank you for these reports. I'm sorry you're experiencing this issue.

On Windows, we listen for suspend/sleep events in order to restore the connection. I have not been able to reproduce this issue on Windows 10; however, I did see a similar issue where the UI was "reconnecting" though I did have a connection through the proxy. I'll look into it some more.

On Linux, we don't yet listen for these events or network connectivity changes. This is on our backlog and we will try to improve it soon.
