While using Server Side Extensions (SSE) or Analytic connections in Qlik Sense, the error Failed to initialize gRPC communication for SSEPlugin is logged
This issue can be identified by reviewing the Qlik Sense Engine logs (How To Collect Log Files From Qlik Sense Enterprise on Windows). They will read:
Failed to initialize gRPC communication for SSEPlugin Python_S3.GenerateSecret
In this message, Python_S3.GenerateSecret is the plugin name.
Resolution
This error means that Qlik Sense could not connect to your Server Side Extension. The root cause is most frequently found in network connectivity. Possible troubleshooting steps to identify the network error are:
- Check the port communication from the Qlik Sense server to the SSE and from the SSE back to the Qlik Sense server. See How To Check Open Ports Using PowerShell.
- Verify if a 3rd-party network appliance (such as a load balancer) is part of the network communication between Sense and the SSE plugin; try testing locally on the Qlik Sense Server to remove this factor.
- In a multi-node installation, verify if this happens from all nodes or only the central node, and verify communication between the rim and central nodes.
- If all the above return good results, test with one of the example SSE plugins to see if the issue persists with the example or if it only occurs with your SSE plugin (to verify if your plugin may be the issue). Precompiled versions of the plugin are available in the Releases section of the repository, but please note that these are not officially supported.
Qlik does not support the configuration or implementation of non-Qlik or Operating System-related software.
Debugging or writing custom code is supported by the Qlik Professional Services or Presales teams. No Support or maintenance is implied or provided. Further customization is expected to be necessary and it is the responsibility of the end administrator to test and implement their custom code for their specific use case.
