# Troubleshooting

## Troubleshooting

If something isn't working as expected, start here. Each page is structured as **Symptom → Likely cause → Fix** so you can scan to your problem quickly.

* verifying-the-installation.md - confirm the module is healthy after install
* connectivity-issues.md - MQTT, REST, certificates, DNS and firewall
* tags-and-data-issues.md - missing tag provider, empty asset tree, counts and events not flowing
* logs-and-diagnostics.md - where logs are, useful loggers, and what to attach when raising a support ticket

{% hint style="info" %}
Before raising a support ticket, please capture the values shown on [Verifying the installation](/tillit/tools/ignition-module/troubleshooting/verifying-the-installation.md) and the relevant log excerpts described in [Logs and diagnostics](/tillit/tools/ignition-module/troubleshooting/logs-and-diagnostics.md). This dramatically reduces the back-and-forth needed to resolve an issue.
