Qlik Sense May 2026 IR contains Virtual Proxy issues regarding "Allow Anonymous" setup

[hugo_andrade]

Hi Qlik Community, 

¡IMPORTANT!

If you are on QAP and leverage anonymous authentication, do NOT upgrade to May 2026 Initial Release.

We have upgraded one of our TEST environments and noticed this issue:

even if the Virtual Proxy is configured to Allow Anonymous Users, they are being prompted for authentication.

So, please check your virtual proxy configuration before upgrading, or wait for the fix.

The Virtual proxies that are configured as Always anonymous users are working as expected.

After upgrading to May 2026 I'm facing issue on QMC:

And another one in the HUB:

Hi @kauenascimento , check this article  for your issue. It's unrelated from the main one.

@hugo_andrade  can you share currect case status? Problem was fixed?

[hugo_andrade]

Hi @korsikov ,

Not fixed. I've applied all patches available and no luck.

@hugo_andrade I'm familiar with this issue a bit as I have a related support case from another customer I've asked R&D to review your post as they have stated this is working as designed as well.

@David_Friend ,

Thank you so much. This is the same challenge I'm facing. RnD seems to be failing to reproduce the issue. I wonder if they are using a virtual proxy with SAML and Allow Anonymous.
