Ios: since v2.25.0 login with qrcode does not work

[solkmaaker]

Expected behavior

Login with QRCODE is successful

Actual behaviour

since v2.25.0 login with qrcode does not work

Steps to reproduce

Install version >2.25 ant try to log in

Reasoning or why should it be changed/implemented?

It's a bug

iOS version

12.4

App version

2.250 (does not matter which version, as long as it is bigger than 2.24.4

Server configuration

Operating system:
Linux

Web server:
Nginx

Database:
Mariadb

PHP version:
7.3.11

Nextcloud version: (see Nextcloud admin page)
17.0.3

Result ia app is:
Error: It is not possible to connect to the server at this time. forbidden

Server log:
"GET /ocs/v2.php/core/getapppassword HTTP/2.0" 403 198 "-" "Mozilla/5.0 (iOS) Nextcloud-iOS/2.25.6"

Revert to web login method works OK, also If i install ios app v2.24.X then qrcode login also works OK.

I can test login with different versions and produce logs/video etc if needed.

Hi, I have create a test and don't exists for we an issue (v 2.25.8)

Hi, tested with v2.25.8.

After scanning QR code, spall spinner rotates a bit, and then, nothing happens, app displays login screen with filled fields (server, username and password), by pressing eye icon, i can see that password field is filled with app password (not main password of user).
I see some requests that have come in to server, all seems to be OK on server side.

At this point login screen (with prefilled credentials) is on phone side. Now i press login button and i'll get same message: "It is not possible to connect to the server at this time. forbidden".
At that time, server log says: "GET /ocs/v2.php/core/getapppassword HTTP/1.1" 403 198 "-" "Mozilla/5.0 (iOS) Nextcloud-iOS/2.25.8"
But when i close app (swipe it up) and then reopen app again - i'm logged in and everything seems to be working.

As for this server log line "GET /ocs/v2.php/core/getapppassword", why does app try to get app password from api?
Since i tried QR code login which contains generated app password (i did not select revert to web login method), app should not try to get app password via api, since i did not give app my main user password (which is needed for generating app passwords according to nextcloud login flow mainual).
Actual responce from server to this api request is:
<?xml version="1.0"?> <ocs> <meta> <status>failure</status> <statuscode>403</statuscode> <message>You cannot request an new apppassword with an apppassword</message> </meta> <data/> </ocs>
Quote: "If the client is authenticated with an app password a 403 will be returned. If the client is authenticating with a real password an app password will be generated and returned."

It's not only login with QR code, here even the "real" password doesn't work properly.
Oviously same problem as in https://github.com/nextcloud/ios/issues/1156

Exactly the same behaviour here, app version 2.25.9

Seems to be fixed in IOS app 3.0.1 and nextcloud server 18.0.7
