Bug with the developer option in OAS 2025 DV

Hello everyone,

We recently upgraded to Oracle Analytics Server (OAS) 2025 and are encountering an issue specifically within the Data Visualization (DV) module. When we enable Developer Mode and click the “Refresh” button, the DV screen enters an infinite loop of authentication pop-ups requiring repeated credentials. Eventually, it becomes unusable unless we force‑quit the browser or application.

Has anyone else encountered this behavior in OAS 2025 DV? Any insights—workarounds, configs, or patches—would be greatly appreciated.

Thanks in advance!

    Hi Dhaval,
    There could be an issue with a front-end configuration (HTTP Server, Load Balancer, Proxy) and the managed server configuration.

    It would be best if you you capture an HTTP Archive (HAR) with your browser web/developer tools.


    SRDC - How To Collect HTTP Archive (HAR) File From Chrome, Microsoft Edge or FireFox Browsers (Doc ID 3035966.1)

    Since a HAR file can include sensitive information, you may want to obfuscate or post it in a secure service request along with information about your authentication and architecture. The HAR file may provide some additional insight into the looping.

    Leaving this here for anyone else to comment on the behavior itself. I have not encountered it, but it may be due to your architectural layers.

    @Dhaval Parikh Stantec I would agree with @SteveF-Oracle - we are not having on our OAS 2025 instances such issue in Developer mode, you are describing (we are having Apache HTTP server in front of OAS, taking care of OAM integration for SSO).

    What Steve and Michal said: didn't have any issue with it with default authentication.

    we have what sounds like the same issue. We have an SR open.

    I tested again with a two-node horizontal scale-out cluster with an Apache HTTP Server front-end.
    It worked fine with accessing each node independently (i.e. - stopping only node2, stopping only node1) via the HTTP Server.

    Key points for this test environment:

    • HTTP only (no HTTPs offloading/termination)
    • Default authenticator (no SSO, no external LDAP). External LDAP should not matter, but SSO configuration possibly.
    • Tested with Safari and FireFox browsers.

    @Dhaval Parikh Stantec - did you ever come to a conclusion / solution?

    @peacey - Opening an SR is the right course of action. Please do provide your architecture/environment/browser details in the SR + HAR file ^^^
