Login attempt just stops

[hajika]

Actual behaviour

I start the app, put in my own server address, "testing connection" appears for half a second, then a NC Screen is shown with a button "Grant Access". I click the button, put in username and password, click login. Then appears "recirecting" and "trying to login". But then the app closes, not completely but Iam back on Home Screen again. When I open the app, there is again the screen to put in the server address.

Password is correct, if I put a wrong password it says to me, that its not correct.

Expected behaviour

I should be logged in and the app should work :)

Environment data

Android version: Lineage OS 14.1, Android 7
Device model: Samsung S4
Nextcloud app version: 2.0.1
Nextcloud server version: 12.04

Logs

There is nothing logged on the webserver corrsponding to this problem, just about the wrong password attempt I tried.

Once before, the app was working perfectly. But then I had to reinstall Lineage after I encrypted the phone and had a boot loop. I don't know if that can be connected somehow to the problem.

I can see via NetMonitor, that the app is still connecting to my server from the background, even when it asks me for my server address when I open it.

Logging in with "nextcloud dev" works by the way..

I am having the same issue.
Stock Galaxy S6.

New (different) login screen that asks me if I want to "Grant my phone Access" to the server.

Inputting user/password just loops and returns to this screen again.

There is also an "Alternative login using app token" option but unsure what that is.

If I let it sit for a minute, it presents a "revert to old login method" option and when pressed it does present the old login screen. Entering user/password does accept input and appears to login but it just loops you back to the beginning.

Nothing in the logs at all.

I managed to stop the loop. There were many Device entries for the same device so I turned the phone off, revoked them all and then restarted the phone (not sure turning the phone off was necessary but I did it anyway). Now I am able to log in...

[hajika]

that unfortunately didn't work for me. I also had a lot of Samsung devices there and deleted them, but still had the same problem. And also, after I did the first "fresh" login attempt, I got two new Samsung devices there.

[pfloor]

FYI: I too have 2 devices that were created at first for my phone. Although only one of them is currently active, the other seems to not have had any activity after it was initially created...

[hajika]

my nextcloud app version is 2.0.1 by the way, do you have the same?

[pfloor]

No, I am on 3.0.0 RC2. This is a testing version that is available.

[hajika]

Where did you get this version? But I guess its similar to the "dev" version that is available on F-Droid (Version 2018-01-21) and also works for me. But its being said, that you should not use this version in production..

[rullzer]

The two new devices was a bug in the server. This is fixed in NC13.

hajika,
From what I understand, there are 3 versions.

1. Production that is on Google Play.

2. Beta (also on Google Play but you must sign up for it) This is the one replaces the production version and provides auto updates. This is the one I use, it is fairly stable...

3. Dev that is available on F-Droid. This one has daily snapshots. You can run it along side the production version but updates are manual. This one may contain lots of bugs, I have never tried it.

@pfloor exactly while to extend your answer the Production version is also available on F-Droid, same goes for the Beta which is offered by F-Droid while F-Droid doesn't actively propagate pre-stable releases. (the dev build is another app where all builds are labelled as "production".)

[hajika]

same goes for the Beta which is offered by F-Droid

that is "nextcloud dev" on F-Droid?

[lars-vom-mars-x]

exactly the same issue on my android m8 lineageOS 14.1 Nextcloud 2.0.1
logcat:

W AccountManagerService: insertAccountIntoDatabase: Account {name=user@host/owncloud, type=nextcloud}, skipping since the account already exists

But i can't find a Nextcloud account?!

Nextcloud dev Version 20180131 has not this issue. After logon i find a "Nextcloud dev" account.
