Ios: Classic Login not working

[Delta-38]

Login Succeeds but Main View isn't loaded. User is forced to close the app, once reopened the transition to Main view is completed correctly.

The issue occurs on several different nextcloud providers I've had the chance to test with

Expected behaviour

After verifying credentials, the Main view should be loaded.

Actual behaviour

WebLogin, infinite spin after clicking Grant Access
ClassicLogin Spinner stops, pressing spinner again gives an error

Steps to reproduce

Install application
Select Classic or WebLogin
Enter correct server, user password credentials
Click Login

iOS version

13.3.1 iPhone
10.3.4 iPad

App version

2.25.8

Operating system:
Debian 10
Web server:
Apache
Database:
MariaDB
PHP version:
7.3
Nextcloud version: (see Nextcloud admin page)
Nextcloud 16.0.7.1

Same here:

I've deleted the App and installed 2.25.8 on two devices with iOS 13.3.1.
I've tried to connect to two NC instances
Instance 1: NC 17.0.3, LDAP/AD
Instance 2: NC 17.0.3, Nexcloud-users only

In all cases (both devices, both NC instances) creating an account in the app failed, both with the NC/AD password and a generated password entered via QR Code.

iOS App reports a "forbidden"

I've collected log records of the non-AD-instance. On the AD-instance it's the same but with more sensitive data:

Update: Same problem with NC staging instance with AD and NC 18.0.1

Another update: The error lets you stop at entering the credentials. If you cancel the app (double click home button and swipe the app out) and restart it, the account actually is open and you can use it.
Once you have done this, you can add additional accounts w/o the error.
The error only occurred when the app was freshly installed, migrating from a working 2.25.7 worked, too.

Persists in app version 2.25.9

[Delta-38]

Some extra information for Marino, login does complete successfully code wise (despite forbidden errors and such, and I can see from logs that my preferences and server information get fetched correctly, the account gets saved correctly and CCMain gets called to load the main view, but it's either an issue with the login controller not popping correctly or the navigation not being carried on successfully in ccmain.
I am running it against NC16, but I also tried a few public servers and always get the same result, I am a little surprised this got so little attention so far.

Same problem here with Nextcloud 18.0.1 (and the previous stable 17.x).

When I try to login with Nextcloud account and password, 403. Same for QR code and same for manually created application password.

I removed the app on the iphone and reinstalled again and worked fine.

Hi, I will do some tests to understand.
Thanks

[marinofaggiana]

TestFlight 2.26.0 <<

[when available]

[Delta-38]

TestFlight 2.26.0 <<

[when available]
I apologize for the delay in getting back to you, I can confirm that with 2.26.0 on Testflight classic login completes successfully.

[Volker-K]

When will it be available outside TestFlight? AppStore still shows me 2.25.9.

[Volker-K]

Will 2.26.0 be available at AppStore at all?

[Ornanovitch]

Is #1188 related ?
Any news on this ?
All my ios users are affected by this issue...

[LiorNevo]

When will 2.26.0 be released?

[Volker-K]

...meanwhile:

2.25.9 works with new browser-based login flow.

QR-Code authentification (what I'd prefer with most end users) ends with a filled form with server name, user id and the generated password. Login ends with an error, that can be ignored if you know how to get out of this trap.
How to excape it? After getting the error, just open task manager (double click the home button), close the app and when you start it again everything is fine.
