Description
Hello,
I setup server on ubuntu 13.04 and client on iPhone 5S (OpenVPN Connect v1.0.2, iOS 7.0.4). When I switch off WiFi? it fails to reconnect, and no websites work. When I switch wifi on it works fine.
Steps to reproduce
- setup a simple vpn server
- While on wifi connect to openvpn server on iPhone
- Open web browser, and make sure everything works fine
- Switch off the wifi
Expected
- VPN icon to blink once and browser working as expected
Actual
- VPN icon goes away, browser cannot open the webpage

I do not understand your reasoning. Why does 4G -> WiFI change works fine then? Shouldn't it also be "unsupported" in the server mode?
For me it really seems that iOS decides to "pause" in that case, instead of reconnecting.

I believe this is a known problem (=bug). Assigning to jamesyonan, who knows the details and can potentially fix this.

Can you reproduce this issue with the latest iOS and OpenVPN Connect release?
comment:6 Changed 9 years ago by
Nope.
It was fixed by the release that mentioned that in the changelog. I assumed that ticket would be closed by now.

Hi
We are developing a VPN application on iOS. We are developing it on C. We are having the same or similar issue as you. When we change from 3g to wifi we can see this wifid error on the logs. Also, we ar eusing C, so we use sendto() to send packets. sendto() returns ENOMEM error.
How did you solve it?
Thanks!!
Note: See
TracTickets for help on using
tickets.
hey eugene,
it seems that even in the open source version of openvpn (as opposed to connect for IOS) this would not work outside of using p2p mode. For that reason I changed this from "bug" to "feature request"
[13:19] <plaisthos> krzee: even float would not help
[13:19] <plaisthos> since float is ignored in non p2p mode
[13:19] <plaisthos> see also the hmac patches for that
