Connection gets stuck on Inactive if switching hosts without disconnecting first

[digitalec]

I’ve been working on troubleshooting a couple of OpenVPN servers and I came across an intermittent issue.

While connected to VPN A, if I switch to VPN B and enable it without first disconnecting from the previous host, the status shows Disconnecting then Inactive. At this point I would expect it to automatically connect to VPN B. Sometimes it will but more often than not it will either stay on Inactive until I manually press Reconnect or the app will crash entirely.

This is the debug log after I switched hosts and it got stuck on Inactive:

Failed LINK read: Error Domain=NSPOSIXErrorDomain Code=89 "Operation canceled"
10:52:02 - Socket state is cancelled (endpoint: xx.xx.xx.xx:1194 -> xx.xx.xx.xx:1194)

@digitalec I remember I had tested and confirmed the issue, but now I can't reproduce it anymore. Can you? How often are you having it?

[digitalec]

I was able to reproduce it every time until I changed the default gateway to Manual and selected only IPv4.

I’m on T-Mobile which is the reason I have to use that setting or else I can’t communicate to any of my local IPv4 addresses. Of course this redirects all traffic through the VPN but I think this requires me to setup IPv6 on my LAN to fix.

Nope, I don't see a relation there. I think it's rather a matter of how long it takes to disconnect. We'll see.

@digitalec please send me an email to beta@passepartoutvpn.app so that I can invite you to TestFlight. There's a chance this might have been fixed as a consequence of fixing #128 and I'd like you to test it, given that I don't experience the issue. Thanks!

However on a second thought I'm pretty sure it won't fix this.

Closing this for inactivity (and not reproducible).
