OpenVPN Support Forum

Hi all,
how can I force OpenVPN connect to resolve the hostname again, when reconnecting (e.g. changed network)?
(If I found where OpenVPN Connects logfiles are saved I would have attached - didn't find out how to get the familiar verbose output)

It keeps trying to connect to the configured servers in an endless loop:

EVENT: RECONNECTING
Contacting OLDIPADDRES via UDP
EVENT: WAIT
Connecting to [hostname] (OLDIPADDRESS) via UDPv4
Contacting OLDIPADDRES via UDP

but it never re-resolves the IP for the hostname, the way it does if I disconnect/connect:
beginning with:

EVENT: RESOLVE
Contacting NEWIPADDRESS via UDP

I need this, because on a local network DNS the configured hostnames are being resolved to another address, public open world IP is not routable in the local network for safety issues. So when I switch from mobile data (using the open world IP) to Wi-Fi (with the local IP) the hostname must be re-resolved.

It was why I switched from openVPN for Android to OpenVPN Connect, because openVPN for Android seems to have configured persist-remote-ip at compile time - or I did not find out how to disable that behaviour.

Thank you all for any hints

problem still present in current version?

is that too complicated

this is such by design. the openvpn app may not have access to a working DNS during a reconnection, therefore it caches all the IP at the beginning.
However, I do understand your particular use case.

Hi Ordex, I really hope we can see this as a feature in the near future.

I've also outlined a detailed post that describes this as well to make it easier for others to find it.

Thank you for your help!

add this in your client openvpn config and forget connect /disconnect , it it do automatic for you whenever you charge network , my android phone just connect all the time no matter wifi or 4g network.

Thanks again for your help...i detailed the final solution in my original thread since this didn't solve the problem.
