+# Troubleshooting
+
+## How to dump the logs
+
+The ComputeHorde software starts several Docker containers. The most relevant logs are from containers with names ending in `app-1`.
+
+To view these logs:
+1. SSH into the machine (validator or miner).
+1. Run `docker ps` to find the name of the appropriate container (e.g., `compute_horde_miner-app-1`).
+1. Run `docker logs CONTAINER_NAME`.
+
+
+## How to restart the services
+
+To perform a hard restart of all ComputeHorde Docker containers, run the following commands:
+
+```bash
+docker compose down --remove-orphans
+docker compose up
+```
+
+Afterwards, use `docker ps` to verify that the containers have started successfully.
+
+## How to fix issues with installing `cuda-drivers`
+
+Miner installation may occasionally fail with an error about the system being unable to install the `cuda-drivers` package. 
+This issue is often caused by mismatched drivers already installed before running the installation script.
+
+To resolve this:
+1. Run the following command on the miner machine to purge any conflicting NVIDIA packages:
+   ```bash
+   sudo apt-get purge -y '^nvidia-.*'
+   ```
+1. Re-run the `install_miner.sh` script from your local machine.
+
+## How to check if NVIDIA Drivers are working and the GPU is usable
+
+To verify the health of the NVIDIA setup, run the following command on the miner machine:
+```bash
+docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi
+```
+
+If the output indicates a problem (especially immediately after installation), a [restart of the services](#how-to-restart-the-services) may help.
