Hi,
I can’t access my Nextcloud AIO interface since my last containers update. I have searched aroud topics with similar problems but couldn’t find a solution. Here is the description of my problem, thanks for helping.
The Basics
- Nextcloud Server version (e.g., 29.x.x):
31.0.7
- Operating system and version (e.g., Ubuntu 24.04):
Debian 12.12
- Web server and version (e.g, Apache 2.4.25):
Apache 2.4.65(nextcloud-aio-apache as well as nextcloud-aio-mastercontainer)
- Reverse proxy and version _(e.g. nginx 1.27.2)
None
- PHP version (e.g, 8.3):
8.3.23
- Is this the first time you’ve seen this error? (Yes / No):
No
- When did this problem seem to first start?
After my last AIO containers update
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
AIO
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
After my last AIO containers update, I can no longer access the AIO interface. The AIO interface displays “Slim application error”.
I have tried to remove then reinstall the mastercontainer :
#As root
docker stop nextcloud-aio-mastercontainer
docker rm nextcloud-aio-mastercontainer
docker run \
--sig-proxy=false \
--name nextcloud-aio-mastercontainer \
--restart always \
--publish 80:80 \
--publish 8080:8080 \
--publish 8443:8443 \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \
--env NEXTCLOUD_DATADIR="/media/data" \
ghcr.io/nextcloud-releases/all-in-one:latest
Then I tried to access my AIO interface by opening https://server-ip:8080/ in my browser.
The last command issues this output :

Trying to fix docker.sock permissions internally…
Creating docker group internally with id 995
Initial startup of Nextcloud All-in-One complete!
You should be able to open the Nextcloud AIO Interface now on port 8080 of this server!
E.g. https://internal.ip.of.this.server:8080
Important: do always use an ip-address if you access this port and not a domain as HSTS might block access to it later!
If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatically by opening the Nextcloud AIO Interface via:
https://your-domain-that-points-to-this-server.tld:8443

Steps to replicate it (hint: details matter!):
- Try to access AIO interface : https://server-ip:8080/containers
