24h provider disconnect with public IP change at dyn dns

[flecka87]

Hello,

i hope anyone can help me.

I use this app under android 14

Here a short overview.
At the original openVPN app. When the public ip was changed the app re resolved my DDNss and got/start with the new IP adress.
But i need split VPN for many Apps.

So i found this app. Everything works well until my provider change the public IP.
The OpenVPN App lost the connection an won't resolve the hostname agian.

It seems thath it is only a configuration issue. but iam not sure.

In the logfile i can see that the client tries to connect to the old IP but he don't trie to resolve the DDNS to get the new IP

the custom opitons are activates an i can see the following

# Config for OpenVPN 2.x
# Enables connection to GUI
management /data/user/0/de.blinkt.openvpn/cache/mgmtsocket unix
management-client
management-query-passwords
management-hold

setenv IV_GUI_VER "de.blinkt.openvpn 0.7.61" 
setenv IV_SSO openurl,webauth,crtext
setenv IV_PLAT_VER "34 14 arm64-v8a OnePlus kona KB2003"
setenv IV_HWADDR 39:38:30:62:61:35:32
tls-cert-profile legacy
machine-readable-output
allow-recursive-routing
ifconfig-nowarn
client
verb 4
connect-retry 2 300
resolv-retry 60
dev tun
remote dyndnsadress.ddnss.de 1194 tcp-client

When the VPN is in this status i can reattached the connetion when i restart it over the APP button.

Below you see the log after the restart is done:

For mi it looks like the APP don't try to resolve the DDNS Adress.

I hope you can help me i realy have no idea, how can i fix this issue.

Thank you.

Do you have persistent-tun enabled? If yes that behaviour is expected.
