Redis connection fails

[time4breakfast]

Description

Hi,
I have the same error as #2115 and I don't know where to start looking.
Any help appreciated.

This is my yaml file:
version: "3.4"
services:
broker:
image: docker.io/library/redis:7
restart: unless-stopped
volumes:
- redisdata:/data

db:
image: docker.io/library/postgres:13
restart: unless-stopped
volumes:
- pgdata:/var/lib/postgresql/data
environment:
POSTGRES_DB: paperless
POSTGRES_USER: paperless
POSTGRES_PASSWORD: paperless

webserver:
image: ghcr.io/paperless-ngx/paperless-ngx:latest
restart: unless-stopped
depends_on:
- db
- broker
- gotenberg
- tika
ports:
- "8000:8000"
healthcheck:
test: ["CMD", "curl", "-fs", "-S", "--max-time", "2", "http://localhost:8000"]
interval: 30s
timeout: 10s
retries: 5
volumes:
- data:/usr/src/paperless/data
- media:/usr/src/paperless/media
- ./export:/usr/src/paperless/export
- /home/anja/paperless-ngx/consume:/usr/src/paperless/consume
env_file: docker-compose.env
environment:
PAPERLESS_REDIS: redis://broker:6379
PAPERLESS_DBHOST: db
PAPERLESS_TIKA_ENABLED: 1
PAPERLESS_TIKA_GOTENBERG_ENDPOINT: http://gotenberg:3000
PAPERLESS_TIKA_ENDPOINT: http://tika:9998

gotenberg:
image: docker.io/gotenberg/gotenberg:7.8
restart: unless-stopped
command:
- "gotenberg"
- "--chromium-disable-javascript=true"
- "--chromium-allow-list=file:///tmp/.*"

tika:
image: ghcr.io/paperless-ngx/tika:latest
restart: unless-stopped

volumes:
data:
media:
pgdata:
redisdata:

Steps to reproduce

What I did:

• installed docker (v. 20.10.21) and docker-compose (v. 1.29.2)
• ran the installation script bash -c "$(curl -L https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/main/install-paperless-ngx.sh)"
• leave all settings on standard (except: using tika and using deu+eng as language)

This is not a bug in the software, it’s something with your setup, just like the other issue. The paperless webserver can’t reach your broker container.

[time4breakfast]

Ok, do I need to setup a broker container in order to use paperless? From your description I assumed that I just have to run the installation script and everything works out fine.
I haven't installed any broker, redis or similar. So where do I need to look in order to fix this problem?

[shamoon]

The install script should setup all of the necessary containers, including redis (named 'broker') but it seems something went wrong. At this point you should have a basic docker-compose, so I suggest you do a little investigating about that and making sure redis is running, can communicate with the webserver container etc.

Self-hosted pretty much always requires some troubleshooting :)

Ok, thanks, that helps to know where to look for a solution :-)

Hello @time4breakfast did you ever figure out what was causing your issue? I am trying to troubleshoot the same and I have tried troubleshooting by turning off firewall, changing my UID to a user with admin access, and trying default and custom networks, However, nothing worked. Looking for some ideas on what to troubleshoot next. Thank you.
