- replace me
Reverse proxy and version _(e.g. nginx 1.27.2)
-swag/nginx 1.26.3
PHP version (e.g, 8.3):
- 8.4.21
Is this the first time you’ve seen this error? (Yes / No):
- Yes
When did this problem seem to first start?
- Upgrade Nextcloud Hub 26 Spring
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
-OMV docker compose

- no,

Summary of the issue you are facing:

I get an empty window without prompt when I launch OCC from the Nextcloud menu. So it impossible for me to use occ command to install Collabora On line Built-in Code server for example. Thanks in advance for any help. Sorry, butI failed to find some configuration file as required to help a faster reply.

Configuration

I add the nextcloud.subdomain.conf file in the swag/nginx/proxy.confs directory

## Version 2025/07/18
# make sure that your nextcloud container is named nextcloud
# make sure that your dns has a cname set for nextcloud
# assuming this container is called “swag”, edit your nextcloud container’s config
# located at /config/www/nextcloud/config/config.php and add the following lines before the “);”:
# ‘trusted_proxies’ => [gethostbyname(‘swag’)],
# ‘overwrite.cli.url’ => ‘https://nextcloud.example.com/’,
# ‘overwritehost’ => ‘nextcloud.example.com’,
# ‘overwriteprotocol’ => ‘https’,
#
# Also don’t forget to add your domain name to the trusted domains array. It should look somewhat like this:
# array (
# 0 => ‘192.168.0.1:444’, # This line may look different on your setup, don’t modify it.
# 1 => ‘nextcloud.example.com’,
# ),
server {

listen 443 ssl;
# listen 443 quic;
listen [::]:443 ssl;
# listen [::]:443 quic;
server_name nextcloud.;
include /config/nginx/ssl.conf;
client_max_body_size 0;
location / {
```
   include /config/nginx/proxy.conf;
```
```
  include /config/nginx/resolver.conf;
```
```
   set $upstream_app nextcloud;
```
```
   set $upstream_port 443;
```
```
   set $upstream_proto https;
```

   proxy_pass $upstream_proto://$upstream_app:$upstream_port;

   # Hide proxy response headers from Nextcloud that conflict with ssl.conf*

   # Uncomment the Optional additional headers in SWAG's ssl.conf to pass Nextcloud's security scan**

# proxy_hide_header Referrer-Policy;
# proxy_hide_header X-Content-Type-Options;
# proxy_hide_header X-Frame-Options;
# proxy_hide_header X-XSS-Protection;
# Disable proxy buffering

```
   proxy_buffering off;
```
}
}

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!):

config.php file:

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.

enable Nextcloud Office: occ app:enable richdocuments
enable Collabora CODE built-in: occ app:enable richdocumentscode

SysKeeper · June 21, 2026, 4:52pm

I fear the issue is that you’re using occweb? Is there shell access available to you?

Didier91 · June 21, 2026, 7:02pm

Hi Syskeeper. Thans for your reply.
Yes I am trying to use OCCweb. Before upgrading to Nextcloud HUB , it worked fine. As I 'm a beginner I am not sure to reply correctly to your second question. For OMV, from which I installed Nextcloud, I use Putty. But for Nextcloud, I don’t know how to put a OCC command.

Didier91 · June 21, 2026, 7:04pm

Hi scubamuc. Thanks for your reply.
I don’t know how to put an OCC command without OCCweb within Nextcloud. Please, is there a way to di it?

scubamuc · June 21, 2026, 7:51pm

its all there in the docs → you need shell access as @SysKeeper mentioned!

so you have shell access to the server

don’t do that as that app is deprecated! see OCC Web - Apps - App Store - Nextcloud , last compatible version was v31 and you’re using v34. better remove that app from your instance.

don’t worry we all started sometime, somewhere, don’t be shy

this thread explains the steps required:
https://forum.openmediavault.org/index.php?thread/44782-using-the-occ-in-nextcloud/

open your putty
connect to server via ssh
enter the container with docker exec -it nextcloud bash
enter the above mentioned occ commands consecutively
- 1. enable Nextcloud Office: occ app:enable richdocuments
- 1. enable Collabora CODE built-in: occ app:enable richdocumentscode

bar having used OMV, you’ll need to wait for some folks who know OMV. be patient…

Didier91 · June 21, 2026, 7:59pm

Thanks a lot scubamu!
