Login stalls at "grant access" with new login method on Docker installation

[bentolor]

Actual behaviour

What does not work:
I cannot pass the step of "grant access" on any device using the Android app.

What does work:

• "Revert to old login method" does work, but blocks the Davx5 integration as well as 2FA usage.
• Login into a differnt server installation works

Expected behaviour

I should be able to login or receive a hint about what's wrong.

Steps to reproduce

I deployed a PostgresSQL / NGinx / Letsencrypt based Nextcloud installation via Docker.

1. With the Nextcloud App (F-Droid. Both version: Stable and Dev) I enter my URL
2. I click Log in
3. I enter my user and password and click Log in
4. I see a Grant access button. I click on this.
5. The activity indicator stays for indefinite.

Environment data

Android version: 9

Device model: OnePlus 3T, LineageOS

Stock or customized system: Vanilla Upstream Docker-based deplyoment

Nextcloud app version: 3.8.1

Nextcloud server version: 17.0.0

Logs

The log starts right before clicking "Grant" and does not change after

@nextcloud/server-triage this seems to be a server-side issue where the forward doesn't seem to work. What do you think?

Upgraded Server to 17.0.1 and Client to 3.9.0 – behavior is still the same.

Anything I can do to support / spot the error? @nextcloud/server-triage

[ThePatricide]

Same happens here. Also problems with Desktop clients. For the desktop clients the workaround followed from here: nextcloud/desktop#1470, which is that you edit the HTML-page (for example with Firefox). The button does a post with 'http', this needs to be 'https' in my case at least and then it works. However, cannot perform this 'trick' on Android, so stuck there unfortunately.

[bentolor]

@bjschuit Thanks for the pointer!

I'm puzzled: If this is really the culprit then it should affect really many and the fix should be really easy…

[MrApplejuice]

I confirm! This is an issue... I am not very sure what is going on... here the access.log of my apache server if that helps anything. I correlated it to the login process from my Android phone. I do not think it is too informative other than given an indication where in the login process things are going wrong:

[Loop: Back to Start-screen]

I am running Nextcloud version 17.0.2.1 on my server, and the client is at version 3.9.2.

One week ago, everything was trill fine. I am uncertain whether I updated my Nextcloud Client in the mean time.

BTW: Happy new year to all! 🎉

Extra info:

• "Revert to old login" does not work for me.
• The Linux client works great!

[MrApplejuice]

Okay... more background. I tried out the dev-client available on F-Droid. That one works just fine. I am not sure if that uses the same configurations and/or data directories compared to the old/stable version, but if it does this issue might be fixed with the new release(?) If it does not, a reset of the the configurations folder (or database? - I do not know much about the app at all) might be a potential fix for the issue.

I just validated the issue with the "Nextcloud Dev Client v20200125" and Nextcloud 18.0. Unfortunately the issue is still present and I can only login using the legacy login method.

[rullzer]

I guess you need: https://github.com/nextcloud/server/blob/master/config/config.sample.php#L451

Beacuse your nextcloud server is behind a reverse proxy. Hence it doesn't know it is on https.
Set that and all should work.
