Quick answer: when you need to troubleshoot Renovate Dashboard 🤖, start with the exact symptom, read the most specific log, verify the affected service, check configuration against runtime behavior, and apply one small fix at a time.

What This Problem Usually Means
Most production issues are not random. They usually come from one of six areas: a stopped service, a wrong port or socket, a permission mismatch, a version conflict, a resource limit, or a slow external dependency. The fastest path is to identify which category fits before changing configuration.
Step 1: Capture the Exact Symptom
Record the error message, URL, user action, server name, and time window. This gives you a stable reference point when you compare application logs, web server logs, database logs, and monitoring data.
date
hostname
journalctl --since "15 minutes ago" --no-pager
tail -n 100 /path/to/site-error.logStep 2: Check the Most Specific Log First
Do not begin by restarting every service. A restart can hide the evidence. Start with the log closest to the failure: Nginx site logs, PHP-FPM pool logs, MySQL logs, application logs, Windows Event Viewer, or the workflow execution history.
Step 3: Verify Runtime State
Confirm that the service is running, listening on the expected port, and using the expected configuration file. Many incidents happen because the operator checks the wrong PHP version, wrong container, wrong virtual host, or wrong environment.
systemctl status service-name
ss -lntp
ps aux | grep service-nameStep 4: Check Configuration, Permissions, and Versions
Compare what the configuration says with what the runtime shows. Check file ownership, socket paths, credentials, API keys, plugin versions, package versions, and environment variables. If the issue started after an update, identify exactly what changed.
Step 5: Review Resource Limits
If the issue appears under load, inspect memory, CPU, disk space, connection limits, worker pools, queue length, and slow upstream dependencies. Raising limits can help, but it should come after you understand why the limit was reached.
Safe Fix Order
- Save the exact error and log window.
- Confirm the affected service and version.
- Validate the port, socket, route, or API endpoint.
- Check permissions and ownership.
- Check resource limits and slow dependencies.
- Apply one fix at a time.
- Verify with logs, HTTP response, and user workflow.
FAQ
Should I restart the service first?
Only if the service is clearly stuck and you already saved the relevant logs. Restarting first may restore the system temporarily, but it can also remove the evidence needed to prevent the next incident.
How do I know whether the fix worked?
Use more than one signal: the command returns successfully, the web request returns the expected status, the log stops showing the error, and the affected user workflow completes normally.
