Hi all, I am very new to nextcloud but I have it set up on my truenas server. I can access it without issue, however when I try to login to the linux or android apps they both sit on authenticating without ever logging in.

## The Basics

- Nextcloud Server version: 31.0.8
- Operating system and version: Pop!\_OS 22.04 LTS
- Web server and version: TrueNAS Community 25.04.2.3
- Reverse proxy and version: None
- PHP version: Unclear what this is
- Is this the first time you’ve seen this error? (Yes / No): Yes
- When did this problem seem to first start? Immediately after installing the apps.
- Installation method: Cosmic Store and FDroid
- Are you using CloudfIare, mod\_security, or similar? No

### Summary of the issue you are facing:

Nextcloud Linux and Android apps never log in. They just keep polling the browser for authentication which it never completes

### Steps to replicate it (hint: details matter!):

1. Install app
2. Enter my server location (ip address:port)
3. Click enter
4. My browser opens (to my truenas login) navigate to my nextcloud web gui and log in.

### Log entries

#### Nextcloud

None available

How are you doing HTTPS?

Please post your config as described in the [support template](https://help.nextcloud.com/t/support-template-please-use-this-when-you-request-support/137402)..

Also before proceeding further, do you have any errors or warnings under _Administration settings-\>Overview_?

Hi, i am not doing any https. Is that necessary? I have been struggling to get a reverse proxy working and so just planned to use tailscale.

Which config do you need? I have posted everything from the template to the best of my ability but am happy to try again if you need something specific.
