Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
My AIO instance is resetting the Nextcloud Office: Collabora Online-server each night during maintenance or updates.
If I change it back to my public domain (which it was set to by the AIO install during deployment), office docs work fine via the browser.
I have found another post from 2024 that’s locked, but I don’t understand their suggested fix, or maybe I didn’t do it right?
Here’s the setting after the nextcloud container restarts or does nightly maintenance:
Here’s the setting after I change it back, making everything work again:
I can’t figure out why it keeps reverting back to the internal apache setting.
I have tried adding an environment variable to the master container docker run, didn’t work. Maybe I did something wrong?
docker run -d \
--init \
--sig-proxy=false \
--name nextcloud-aio-mastercontainer \
--restart always \
--network nextcloud-aio \
--publish 8880:8080 \
--env APACHE_PORT=11000 \
--env APACHE_IP_BINDING=0.0.0.0 \
--env APACHE_ADDITIONAL_NETWORK="" \
--env SKIP_DOMAIN_VALIDATION=true \
--env NEXTCLOUD_DATADIR="/mnt/sda1/docker_mounts/nextcloud" \
--env NEXTCLOUD_KEEP_DISABLED_APPS=true \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \
-v /etc/pki/ca-trust/source/anchors:/usr/local/share/ca-certificates:ro \
-v /etc/pki/tls/certs/ca-bundle.crt:/etc/ssl/certs/ca-certificates.crt:ro \
--env NEXTCLOUD_TRUSTED_CACERTS_DIR=/mnt/sda1/docker_mounts/nextcloud/trusted_ca_certs \
--entrypoint "/bin/bash" \
ghcr.io/nextcloud-releases/all-in-one:latest \
-c "update-ca-certificates && /start.sh"
Something interesting I found in the nextcloud container env (though I don’t know the interworkings of the code) is this:
Inspect nextcloud-aio-nextcloud:
env:
"NEXTCLOUD_EXEC_COMMANDS=echo 'Activating Collabora config...' php /var/www/html/occ richdocuments:activate-config --wopi-url='http://nextcloud-aio-apache:23973' --callback-url='http://nextcloud-aio-apache:23973' ",
There is a caddy container on the docker server:
cat Caddyfile
cat Caddyfile
# Disable Caddy’s automatic HTTPS (no ACME, no Let’s Encrypt)
{
auto_https off
}
https://nextcloud.ccac.candiamantics.net:443 {
# Use the locally-provided certificate pair
tls /certs/cert.pem /certs/cert.key
# Remove server banners
header -Server
header -X-Powered-By
# Proxy everything to the Apache container inside the bridge network
reverse_proxy nextcloud-aio-apache:11000
}
The Basics
- Nextcloud Server version (e.g., 29.x.x):
- Nextcloud Hub 10 (31.0.10)
- Operating system and version (e.g., Ubuntu 24.04):
- NAME=“Rocky Linux”
VERSION=“9.6 (Blue Onyx)”
- NAME=“Rocky Linux”
- Web server and version (e.g, Apache 2.4.25):
AIO builtin
- Reverse proxy and version _(e.g. nginx 1.27.2)
Caddy
- PHP version (e.g, 8.3):
AIO latest
- Is this the first time you’ve seen this error? (Yes / No):
No, each night
- When did this problem seem to first start?
Unknown, long time after an automatic update by master container
- 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:
AIO instance is resetting the Nextcloud Office: Collabora Online-server each night during maintenance or updates.
Steps to replicate it (hint: details matter!):
-
Set the correct Collabora Online-server
-
Restart nextcloud-aio-nextcloud
-
Collabora Online-server has reverted to internal apache URL
