How to enable Constellation in on-premise environment
Hello,
We have just installed Pega Platform 25 in on-premise environment. Then, I have opened Work Portal and it gets blank page as below.
In the PegaRULES.log, I see below error messages:
2026-02-09 23:15:11,800 [http-nio-8080-exec-8] [_Developer] [ ] [ MySandbox:01.01.01] (11nBuildInfo._baseclass.Action) ERROR localhost| Proprietary information hidden HW8XY0JO7RHTOTT0SF0IPD9033RP4LGAKA cloe.walker - Exception fetching buildinfo.json: Failed to connect to / Proprietary information hidden:3000
java.net.ConnectException: Failed to connect to / Proprietary information hidden:3000
at okhttp3.internal.connection.RealConnection.connectSocket(RealConnection.kt:297)
...
I am assuming I need to get some additional UI modules for Constellation from Pegasystems. Am I correct? If so, where and how should I do that?

Have you set the ConstellationPegaStaticURL DSS to reference the Constellation Pega Static Service?
As described in the documentation linked below this should either be set to use the Constellation Pega Static CDN (https://release.constellation.pega.com) or if you cannot use the Constellation Pega Static CDN because you require your deployment to be air-gapped, you can deploy the Pega Static Service in your organization's infrastructure using a Pega-provided Docker image.

Thank you for your response. However, I have already configured the DSS as below:
FYI, if above DSS is not configured, different screen pops.
Hence, I think this issue is not about DSS. Please let me know what could be the possible root cause.

You will need to review the network trace when logging into this portal and inspect the failed calls. Is the endpoint that is failing the CDN url?
