The Basics
- Nextcloud Server version (e.g., 29.x.x):
- 32.0.0
- Operating system and version (e.g., Ubuntu 24.04):
- Debian GNU/Linux 12
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- Docker AIO
Summary of the issue you are facing:
The nextcloud-aio-collabora container accesses the master container via reverse proxy rather than internally within the Docker Network.
Steps to replicate:
-
Packet capture going towards reverse proxy: sudo tcpdump -i any host {Proxy IP}
-
Correlate logs with actually container:sudo docker network inspect {Docker Network} | grep -B5 {Container IP Identified}
Log entries
Packet Capture excerpt:
*14:36:00.098526 br-**cfa8884114e4** In IP **172.20.0.3**.57776 > **{Proxy IP}**.https: Flags \[R\], seq 2027403687, win 0, length 0*
Correlation:
*sudo docker network inspect cfa8884114e4 | grep -B5 172.20.0.3
