+# Troubleshooting common issues
+
+This guide collects practical troubleshooting workflows for Shopware PaaS Native. It focuses on checks you can perform with the CLI, Grafana, and an application shell session.
+
+## Prepare your CLI context
+
+If you regularly work with the same organization, project, or environment, set a default context first:
+
+```sh
+sw-paas account context set
+```
+
+You can also preselect the default environment for the current shell session:
+
+```sh
+export SW_PAAS_ENVIRONMENT=staging
+```
+
+This avoids repeated prompts while you troubleshoot. For more details, see the [account guide](../fundamentals/account.md).
+
+## Check timing and trace headers
+
+If a page is slow, intermittently returns an error, or seems to be cached, inspect the current response timings first:
+
+```sh
+sw-paas app timing --query "foo=bar"
+```
+
+Adding a query parameter helps bypass cached responses so you can inspect a fresh request.
+
+The following response headers are especially useful:
+
+| Header | Meaning |
+| ------ | ------- |
+| `x-envoy-upstream-service-time` | Time spent inside the Shopware PaaS Native infrastructure for the upstream request |
+| `x-trace-id` | Trace identifier that you can search for in Grafana Tempo |
+| `x-timer` | Fastly timing information. The `VE` value helps estimate the time between Fastly and the origin infrastructure |
+
+You can also inspect the same headers in your browser's network tab.
+
+## Check logs and traces in Grafana
+
+Once you have confirmed the failing request, continue with logs and traces:
+
+```sh
+sw-paas open grafana
+```
+
+Use [logs](../monitoring/logs.md) to inspect application output and [traces](../monitoring/traces.md) to follow the request path through the system.
+
+If you already captured an `x-trace-id`, search for that value directly in Tempo to jump to the affected request.
+
+## My deployment finished, but the changes are not live
+
+If an update appears to have completed but the application still serves the old state, inspect the application first:
+
+```sh
+sw-paas application get --application-id <application-id>
+```
+
+The `updated` timestamp is a useful indicator. If it does not change after you triggered the update, inspect the build logs:
+
+```sh
+sw-paas application build logs --application-id <application-id>
+```
+
+For the general deployment workflow, see the [applications guide](../fundamentals/applications.md).
+
+## Scheduled tasks or queue workers are stuck
+
+If scheduled tasks remain in `queued` state for too long, start with the worker logs in Grafana. If the logs do not explain the issue, open an application shell:
+
+```sh
+sw-paas exec --new
+```
+
+From there, run the consumers manually to surface runtime errors:
+
+```sh
+bin/console messenger:consume async low_priority failed scheduler_shopware
+```
+
+If scheduled tasks are missing after a deployment or update, register them again:
+
+```sh
+bin/console scheduled-task:register
+```
+
+If you need to inspect the database state directly, open a database tunnel as described in the [database guide](../resources/databases.md).
+
+## What to collect before opening support
+
+If the issue is still unresolved, collect the following information before opening a support request:
+
+- The affected application ID
+- The failing URL
+- The approximate timestamp of the failing request
+- The `x-trace-id`, if available
+- Relevant build or deployment log excerpts
