Welcome to Microsoft Q&A platform and thanks for posting your question here.
There could be several reasons why a self-hosted integration runtime is unavailable. Here are some common causes and recommendations to fix the issue:
- The first step to troubleshoot an unavailable self-hosted integration runtime is to check the logs for any errors that can help identify what the issue is.
- Ensure that the self-hosted integration runtime is properly configured and connected to your data factory. Check if the integration runtime can connect to the cloud service. If not, this issue is usually caused by network settings in the firewall.
- Sometimes, simply restarting the integration runtime can resolve the issue. Try restarting the integration runtime and check if it resolves the issue.
- Utilize the self-hosted integration runtime diagnostic tool available from the Configuration Manager to identify any issues. Run the diagnostic tool and follow the instructions to fix any issues that are identified.
- Verify that the Integration Runtimes service is active in the services section of your operating system. If the service is not running, start the service and check if it resolves the issue.
- In case the self-hosted integration runtime remains unavailable even after trying the previous troubleshooting steps, you need to consider uninstalling and reinstalling the integration runtime.
