channel produced error: error reading magic number: EOF

Hi.

I'm trying to install GRR with docker compose with following guide

• https://grr-doc.readthedocs.io/en/latest/installing-and-running-grr/via-docker-compose.html

These are my system informations

• OS: ubuntu 24.04.
• Docker version: 29.2.1
• Docker-Compose version: v2.5.0

When I do 'docker-compose up -d', my grr-client has problem (unhealthy)

NAME                      COMMAND                  SERVICE                   STATUS                PORTS
fleetspeak-admin          "server -components_…"   fleetspeak-admin          running               4444/tcp
fleetspeak-frontend       "server -components_…"   fleetspeak-frontend       running               10000/tcp
grr-admin-ui              "/bin/bash -c '/conf…"   grr-admin-ui              running (healthy)     0.0.0.0:8000->8000/tcp, :::8000->8000/tcp

grr-worker                "grr_server -compone…"   grr-worker                running

And it shows following logs
E0210 08:21:32.208785 2210 system_service.go:251] Unable to get revoked certificate list: unable to retrieve file, last attempt failed with: failed with http response code: 404

I don't have any knowledge for fleetspeak, but I desperately hope to install and use GRR.
Could someone please give any hint or solution for this problem?
