WiFiUnavailableError when using RethinkDNS

[vesahc]

Description

Ente will not connect with Rethink enabled, but connects fine with it disabled. I've tried whitelisting every DNS and IP used by Ente without success. There's been no other updates made to the Rethink config in months and Ente is the only app I'm noticing issues with.

I'm not sure if this started happening with the most recent release, or the upgrade to Android 15.

Version

v0.9.53

What product are you using?

Ente Photos

What platform are you using?

Mobile - Android

Hey, it seems that RethinkDNS is somehow blocking ente. Have you self hosted Ente ? If so, you should check if the ports for museum (ente's server) are whitelisted.

Also, please show what is the error you're seeing in the ente's logs. can you also please share any steps to try replicate the issue, I have installed RethinkDNS on my device (and I'm running a self hosted ente instance).

Hi @mngshm, thanks for your response.

No, I haven't self hosted. I've tried allowing every IP/DNS address that Ente uses in Rethink.

I've also tried downgrading to an older Ente version that previously worked and am experiencing the exact same issue.

On a fresh install, everything works as expected. I can log into the account, it syncs fine and pulls everything from the server. The issues seem to start when it gets to uploading. The status bar changes to "Waiting for WiFi..." and never changes from this point unless it syncs items in. I can add a photo in the desktop app, the mobile app will change to syncing briefly to pull the photo then switch back to "Waiting for WiFi...".

What's confusing me is that when Rethink is blocking it then I can't even sign into the app, and it will not sync down from the server. I just confirmed by blocking it in Rethink, the added photo syncs down immediately after I unblock it.

Looking at the history of when it stopped uploading it looks like this started shortly after I upgraded to Android 15. (GrapheneOS). Will try a fresh install in another profile when I get a chance.

Mentioned error is below along with the entire log.

Hi,

In backup settings could you please toggle the "Backup on Mobile Data" option and see if you still have this issue. Ideally, looking at the code in

ente/mobile/lib/utils/file_uploader.dart

Line 414 in d4587ab

Future<void> checkNetworkForUpload({bool isForceUpload = false}) async {

Confirming that when toggling everything appears to work as per normal. Behaviour appears to revert when re-toggling the option.

Does ente (on Android) bind to a network (via ConnectivityService.bindProcessToNetwork or Network.bindSocket or equivalent POSIX syscalls)? This won't work if an active VPN app disallows "bypass" (ref).

On Rethink's end, an end-user can allow bypass by turning ON Configure -> Network -> Enable network visibility (do not recommend turning it ON at all, but okay for testing connectivity issues).
