App doesn't work with self signed certificates

[soda-pop-ice-cream]

Hi there!
App doesn't want connect to server that using self signed certificates (added to device and trusted ofc), all apps on devices work well with them.

Hi, I think I know which config is missing, but I can't test it myself.
Could you install the app via the Play Store?
Then I would invite you to a beta program there so that you can test the change quickly.
Is that okay?

[KevinCFechtel]

I would also need the email address of your Google account that you use to install the app.
I would then authorize this address in the beta program.
You can send it to me by e-mail: [email protected]

Sure, email sent. 👍

[KevinCFechtel]

The update is now published in the beta program, you should be able to install it via the following link.
The SSL certificates added by the user should now also be trusted.
A short feedback if it works now would be great, then I will create the official release.

I installed 1.4.3 beta, and sadly it didn't help.. 🫠

Too bad, is your server accessible from the Internet by any chance?
If so, could you email me the URL so I can see if I can get a request through.
Otherwise it would be a lot of try and error.

I set you up dev environment on spare vm, emailed url and creds 👍️ Let me know if i can help with something too(like webserver logs, etc)

Thanks, it looks like it's a general problem with Flutter/Dart though....
dart-lang/sdk#50435
I'll see how I can change the HTTP calls, maybe a new http client could be used.

[KevinCFechtel]

The following issue is currently still blocking implementation dart-lang/http#1179

[KevinCFechtel]

I have changed the http implementation of the miniflux backend so that user trusted certificates are now also integrated.
However, I am currently still having problems with the cronet version without Google Play Services.
Therefore, I have only set a beta test of the new version for now, the real release will follow as soon as a version without Google Play Service dependencies can be created.
You should now see an update of the app in the Play Store, please check again whether the self-signed certificate works with this update (in my test at least it did 😊)

Indeed, it works now! 🎉 I didn't even removed my "non-working" settings, just updated and restarted app. 🙂
Thank you!
