Tried again with new app pass and after restarting phone no go

What debug steps shall I proceed with?

[thomas-merz]

The same here:
I already stopped the Nextcloud App, turned my iPhone off and on again. But still no login is possible with Nextcloud App 2.24.1 and iOS version 13.1.2. Than I upgrade to iOS version 13.1.3.
But it's still stuck at "Grant access"... :-(
Nextcloud App 2.24.3 (which seems to be the most current version) is not available at the moment in the App Store.

Wild stab in the dark based on a similar issue I remember having once: Try dismissing the iOS keyboard before you tap any login or grant access buttons?

Tried good idea, didn’t work

[fermulator]

Is there a better way to raise attention to this? Who’s the owner of the iOS functionality? Or does it fall to open source community?

[ps-git]

Assuming you are:

• running your own webserver
• with HTTPS redirection (all HTTP requests redirected)

Can you please confirm that you set the:
'overwriteprotocol' => 'https'

in config/config.php

I had a similar issue in the webbrowser, and this fixed it when running via a reverse proxy.

[fermulator]

It is set correctly, yes

@nextcloud:/etc$ sudo grep https /srv/nextcloud/config/config.php
  'overwriteprotocol' => 'https',
  'overwrite.cli.url' => 'https://nextcloud',

EDIT: also back-updated the original post with full server-side details

I got the same issue with NGINX reverse proxy, which was related to HTTP/2 handling of IOS devices.

Solved it by adding proxy_hide_header Upgrade; within the location part of the configuration. I think you can do this in apache2 with Header unset Upgrade;

[thomas-merz]

Hi @paulluijben , I'm really no nginx-expert. So I tried your hint and added this to "location /" and restarted my nextcloud (docker-compose restart). But the problem still exists with iOS-App-Version 2.24.4 :-(

[paulluijben]

Hi @thomas-merz, this only works in case you are using an reverse proxy in front of your Nextcloud instance.

Solved my problem perfectly, Thanks very much.

[thomas-merz]

Problem is still existing with 2.24.4 now! 👎 Who can help with this?
Is this a problem with the iOS App, the Nextcloud Server or what can I do to get connected again with my Nextcloud?
I also found this (old) thread on help.nextcloud.com

did not work for me, did it like this:

# Nextcloud
ProxyPass /cloud https://nextcloud:443
ProxyPassReverse /cloud https://nextcloud:443

<Location /cloud>
    # nextcloud:
    # https://github.com/nextcloud/ios/issues/960
    Header unset Upgrade
</Location>

Latest version updates

• nextcloud iOS 2.25.0
• iOS = 13.2.3

[fermulator]

UPDATE: (SUCCESS)

It's been a while since I conducted any maintenance on the server back end. Due to v14 unsupported status recently, I fired through the serial updates v14 -> v15 -> v16 -> v17.

After this, my instance continued to work from a web-UI perspective (great!).

Then i (on a whim) decided to retest this. Now it's working! Versioning info is now:

• nextcloud v17.02
• iOS v13.3
• nextcloud iOS app v2.25.3.6

So not sure if it was that minor app version bump, or the backend server having an incompatibility with the iOS app... but for me it is working now!

Keen to hear if others have similar success based on this information.

[philffm]

Still had trouble on v17.02 with iOS v13.3 - proposed solution by @paulluijben worked like charm! Wonderful, I love this community!

Also works easily with NGINX proxy manager

[jmou]

Worked for me on Apache with RequestHeader unset Upgrade

[eivl]

Worked for me on nginx with the RequestHeader unset Upgrade config under location
proxy_hide_header Upgrade;
