  - `nginx 1.26.3`

- PHP version _(e.g, 8.3)_:
  - `php 8.4.23`

- Is this the first time you’ve seen this error? (Yes / No):
  - `Yes`

- When did this problem seem to first start?
  - `During Nextcloud Office setup, on ~/index.php/settings/admin/eurooffice form page`

  - `Bare Metal`

- Are you using CloudfIare, mod\_security, or similar? _(Yes / No)_
  - `No`

### Summary of the issue you are facing:

I have Euro-Office document server ([version 9.3.1](https://github.com/Euro-Office/DocumentServer/releases#release-v9.3.1), manually downloaded and installed the amd64 release), running on port :80. My Nextcloud instance works nad is running on port :81. I can curl http://:80 & :81 successfully with no errors in the terminal.

As per the integration instruction here: [GitHub - Euro-Office/eurooffice-nextcloud · GitHub](https://github.com/Euro-Office/eurooffice-nextcloud) , I navigate to `~/settings/admin/eurooffice` in the Nextcloud web application, and fill out the form as follows:

Nextcloud Office Address: `http://<server-ip>:80/`

✓ Disable Certificate Verification

Secret Key: Retrieved from `/etc/euro-office/documentserver/local.json`

When I submit the form, I get the error below:

`Request Failed with Status Code 500`

I’ve tried changing from port :80 to :8080, restarting nginx, restarting my server, reinstalling euro-office

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

1. Change Nextcloud port with `sudo snap set nextcloud ports.http=81`

2. Install Euro-Office 9.3.1 as per the [documentation](https://euro-office.github.io/documentation/installation/debian/)

3. Install eurooffice-nextcloud as per the [documentation](https://github.com/Euro-Office/eurooffice-nextcloud)

4. Retrieve JWT secret from ``/etc/euro-office/documentserver/local.json``

5. Navigate to `~/settings/admin/eurooffice` in the Nextcloud web application. App directory is: ``/var/snap/nextcloud/current/nextcloud/extra-apps``

6. Nextcloud Office Address: `http://<server-ip>:81`, ✓ Disable Certificate Verification, set JWT secret

7. `Request Failed with Status Code 500`

#### Web server / Reverse Proxy

The output of your Apache/nginx/system log in `/var/log/ ____ `:

```auto
PASTE HERE

```

### Configuration

#### Nextcloud

The output of `occ config:list system` or similar is best, but, if not possible, the contents of your `config.php` file from `/path/to/nextcloud` is fine (make sure to remove any identifiable information!):

```auto
PASTE HERE

```

#### Apps

The output of `occ app:list` (if possible).

### Tips for increasing the likelihood of a response

- Use the `preformatted text` formatting option in the editor for all log entries and configuration output.
- If screenshots are useful, feel free to include them.
  - If possible, also include key error output in text form so it can be searched for.

- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

The error message indicates, that one file is missing in your Euro Office integration app. Try removing it completely and reinstalling it.

Wild guess: something related to Snap confinement. The EO docs are for a bare metal installation.

Does this file actually exist? It likely would have been created after running Composer. Though I have no zero idea how Composer interacts with Snap’s environmental assumptions and constraints.

@guy123 welcome and thanks for your request 👋

your setup is unclear from the information you’ve mentioned:

- nextcloud snap installed on bare metal host behind nginx reverse proxy on the same host, right?
  - FQDN correctly configured as per [How to manage Hosts and FQDN for Nextcloud snap](https://help.nextcloud.com/t/how-to-manage-hosts-and-fqdn-for-nextcloud-snap/216109), right?

ergo, Nextcloud snap is running on a port other than 80 (which port is that?) → nginx reverse proxy is internet facing on ports 80 and 443 forwarding the snap and doing the SSL stuff.

its unclear how you’re installing eurooffice though… assuming its a bare metal install on that same host using \*.deb or make, you’d need to configure a port other than port 80 (nginx), port 8x (Nextcloud snap) and configure a proxy host in your reverse proxy, forwarding that eurooffice port.

but those are assumptions and without details we’re just guessing.

recommend running eurooffice in a docker container on that host see [Euro Office for Nextcloud with Docker](https://help.nextcloud.com/t/euro-office-for-nextcloud-with-docker/246602) that way you’re not interfering with the snap and you’ve separated the snap and eurooffice environments, each running in their own contained environment and letting nginx handle the routing and SSL

@jtr the eurooffice app from the app store is merely complaining that it can’t connect to the service that was configured in the adminsettings

 ![image](https://help.nextcloud.com/uploads/default/original/3X/6/6/667f55e47ce56b8c540b24010af1c42183a540a4.png)

→ so its not a confinement issue as the eurooffice service is not running within the snap and confinement will only effect binaries executed within the snap.

personally been running [eurooffice](https://help.nextcloud.com/t/euro-office-for-nextcloud-with-docker/246602) and [collabora](https://help.nextcloud.com/t/collabora-code-for-nextcloud-with-docker/216725) in parallel on the snap for a while now, without any issues.

thus @guy123 should be able to run all those services on one host, provided the services are each correctly configured and the nginx proxy hosts are forwarded correctly.

OP was a little unclear; they linked to the docs for installing from the repo not via the app store so I was responding from that perspective.
