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 named librechat_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 try http://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 to deploy-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 has HOST=0.0.0.0 and NODE_ENV=production.

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.). The api 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.
