Qlik Sense failed to connect Server Side Extension(SSE) with error code 14 for R integration

[JinNgiu]

Dear community,

We're integrating Qlik Sense Enterprise on Windows with R.
This is a single node site, Qlik Sense and R are installed in the same server.

1. The integration was working fine with Qlik Sense Nov 2024 version.
2. However, it failed after Qlik Sense has been upgraded to May 2025 version.
3. RServe and the SSE plugin – SSEtoRServe were both running and listening to the correct ports.
4. The SSE_Engine log returns: Failed for localhost:50051 error code : 14

SSE plugin downloaded from:
https://github.com/qlik-oss/sse-r-plugin

Everything is the same except the Qlik Sense version, but the issue arise.

We'd be appreciate it if you could advise on this.

Thanks,

Regards,

JN
