Troubleshooting LibreChat Access on localhost:3080
Based on your logs, the Docker images pulled successfully (after some initial timeouts and retries), and 6 components started: the default network, vectordb
, chat-mongodb
, chat-meilisearch
, rag_api
, and LibreChat
. However, the api
service (which typically serves the backend on port 3080) isn’t listed in the started containers—this is likely why you can’t access the site. The LibreChat
container is probably the frontend, which depends on the api
backend.
The UID/GID warnings suggest potential permission issues that could prevent the api
container from starting properly. Here’s a step-by-step guide to diagnose and fix this.
1. Verify Running Containers and Ports
Run this to see all active containers, their status, and port mappings:
docker ps
- Look for an
api
container (it might be namedlibrechat_api
or similar). If it’s missing or exited, that’s the issue. - Confirm if port
3080
is mapped (e.g.,0.0.0.0:3080->3080/tcp
). If not, the service isn’t exposing it. - If no containers show port 3080, proceed to the next steps.
2. Check Container Logs
Inspect logs for errors in startup, especially for the api
and LibreChat
services:
docker logs LibreChat
docker logs api # Or docker logs librechat_api if named differently
docker logs rag_api # In case of dependency issues
- Common errors: Permission denied (due to UID/GID), MongoDB/Meilisearch connection failures, or binding issues (e.g., not listening on 0.0.0.0).
- If logs show the server starting but binding only to localhost inside the container, add
HOST=0.0.0.0
to your.env
file.
3. Set UID and GID to Fix Permission Warnings
Your .env
file (copied from .env.example
) likely has these vars commented out. Unset vars can cause containers to fail silently due to file permission mismatches.
- Edit
.env
:UID=1000 # Run `id -u` to get your user ID GID=1000 # Run `id -g` to get your group ID
- Save, then restart:
docker compose down docker compose up -d
This ensures volumes (like config/logs) are owned by your user.
4. Test Connectivity
- Check if port 3080 is listening locally:
curl -v http://localhost:3080
- If it times out or refuses connection, the service isn’t running/exposed.
- If
docker ps
shows the port mapped but curl fails, check firewall (e.g.,sudo ufw status
) or tryhttp://127.0.0.1:3080
.
5. Additional Fixes if Needed
- Image Pull Issues: Your first attempt had a “denied” error for
ghcr.io/v2/librechat/librechat/manifests/latest
. If pulls fail again, authenticate with GitHub Container Registry:echo $YOUR_GITHUB_TOKEN | docker login ghcr.io -u YOUR_GITHUB_USERNAME --password-stdin
(Create a personal access token at github.com/settings/tokens with
read:packages
scope.) - Use the Recommended Compose File: The default
docker-compose.yml
is for local builds, which can be finicky. Switch todeploy-compose.yml
for stable remote images:- Rename or backup your current
docker-compose.yml
. - Use
deploy-compose.yml
instead:docker compose -f deploy-compose.yml up -d
. - Ensure
.env
hasHOST=0.0.0.0
andNODE_ENV=production
.
- Rename or backup your current
- Full Restart with Prune: If stuck, clean up:
docker compose down -v # Removes volumes too docker system prune -f docker compose up -d
- Dependencies: Confirm MongoDB and Meilisearch are healthy (
docker logs chat-mongodb
, etc.). Theapi
depends on them.
After these steps, retry accessing http://localhost:3080. If logs show specific errors (e.g., Mongo connection), share them for more targeted help. This setup works for most users once UID/GID and dependencies are sorted.
