Error when logging into Qlik Replicate Console

[iti-attunity-sup]

Hello Support Team.

I hope you are doing well.

I am writing to report a login issue we are experiencing with Qlik Replicate 2025-11 after installing it on Windows Server 2025.

Issue Description: After entering the username and password on the login screen, the console displays an error (please see the attached screenshot) and fails to log in.

Investigation so far:

• System Requirements: I have attached the evidence confirming that all installation requirements have been met.

• Cookies: Based on our initial investigation, we suspected it might be related to browser cookies. However, clearing the cookies and attempting to log in again resulted in the same error. The issue remains unresolved.

Could you please review the attached error details and the environment evidence, and provide guidance on how to resolve this?

Best regards.

Hello @iti-attunity-sup ,

I installed Windows Server 2025 Standard, but I was not able to reproduce your issue.
However, if I disable cookies, the Replicate Console immediately logs out.

Strictly speaking, Windows Server 2025 itself has not changed the HTTP cookie standard, but it comes with a stricter security baseline, which is key:

• Stricter TLS / HTTPS policies by default

• Stricter browser security policies (especially in enterprise environments)

I recommend disabling Enhanced Tracking Protection in Firefox to test whether it is causing the issue. You can also compare with other browsers:

• Try Chrome / Edge

If they work normally, it is likely a Firefox policy issue rather than a Windows issue.

Regards,

John.

Hi @iti-attunity-sup ,

Please also try the following and share the results:

• Using Firefox in Private Window mode
• Qlik Replicate’s FORM authorization

Thanks,
Desmond

Hello, @john_wang @DesmondWOO 

Thank you for your response.

Even after allowing all cookies,

I was still unable to log in. I also tried using Chrome and Microsoft Edge,
but the same error occurred. The issue persisted even in Private Window mode.

However, after rebuilding the environment from scratch,
I was finally able to access the console.
Therefore, I am closing this issue.

Best Regards.
