# Troubleshooting ## Service Not Reachable Check service status: ```bash systemctl status clicd journalctl -u clicd -n 100 --no-pager ``` Check port listening: ```bash ss -lntp | grep 8999 ``` If a reverse proxy is used, check proxy logs and upstream address settings as well. ## Image Download Failed - Make sure the host can access image sources and GitHub Releases. - Check disk space. - Review the failure reason in the task queue. - If a download is stuck, cancel it and start again. ## Container Cannot Access the Network - Check host NAT and forwarding rules. - Confirm that the container IP was assigned successfully. - Check whether the firewall is blocking forwarded traffic. - For IPv6, confirm that the upstream network routes the prefix to the host. ## WebSSH or WebVNC Connection Failed - Confirm that the container or virtual machine is running. - WebSSH requires SSH service inside the container. - WebVNC requires the KVM console to be reachable. - Tickets expire quickly. Create a new ticket after expiration. ## API Returns Unauthorized - Confirm that the API key is not disabled. - Use `X-API-Key` or `Authorization: Bearer`. - Confirm that the key scope covers the target endpoint. - Do not use the panel login password as an API key.
