[BUG] - Cannot reconnect when my router IP changes

[kslcsdalsadg]

Describe the bug

I use Wireguard to connect to my wireguard server, at my home.
My ISP provider changes my IP address 2-3 times a day.
I have configured the wireguard connection settings to use a DNS name instead of a IP and I have a service in my house that syncs the IP address of my router to cloudflare each time my IP changes.
When my IP changes, your app seems not capable to reconnect and icon at left to the name remains in yellow until I manually disconnect then reconnect again, even if I set reconnect if ping fails to True.
You are catching IP address and use the cached IP address to reconnect instead of resolve the DNS name each time?

Smartphone (please complete the following information):

• Device: [e.g. Pixel 4a] Pixel 7 Pro
• Android Version: [e.g. Android 13] 15, GrapheneOS
• App Version [e.g. 3.3.3] 4.6.6
• Backend: [e.g. Kernel, Userspace]

Hello! It should be re-resolving the IP address when we bounce the tunnel on ping failure.

I'm trying to determine if the ping feature is not working properly or if the dns is indeed cached.

Do you see these tunnel bounces/restarts happen at all?

Hello
It restarts when I disable the tunnel then automatic tunnel chck then re-enable automatic tunnel

Hello It restarts when I disable the tunnel then automatic tunnel chck then re-enable automatic tunnel

So it seems like the pinger is not restarting the tunnel when the ping fails or something is happening where the ping job is not running. So it is likely not a caching issue. Is that correct?

[kslcsdalsadg]

Maybe

Hey! Just wanted to follow up on this one.

Is this issue resolved?

[zaneschepke]

I looked into this a bit deeper and it seems, depending on the OS, caching may be causing this issue. I'm going to implement from mitigation measures to help with this.

Fantastic! I will try the new app version when released then comment here. Thanks for your support

Could you give this a try when you get a chance and see if it helps?

I will try it. Thanks

Off topic: What are the differences BTW normal and fdroid app versions?
