Monitoring apps fail with : Connection ... not found ; after enabling SSO (SAML/Entra ID)

[hamid]

Hi,

We're running Qlik Sense Enterprise on Windows, November 2025. Since IT enabled SSO (SAML) on the server, all  monitoring apps (Content Monitor, License Monitor and Operations Monitor) fail to reload with the following errors.:

Content Monitoring --> Connection 'monitor_apps_REST_app' not found

License Monitor --> Connection 'monitor_apps_REST_license_user' not found

Operations Monitor --> Connection 'monitor_apps_REST_user_condensed

What we've already checked/tried, without success:

• The data connections (e.g. monitor_apps_REST_*) exist in the QMC, correctly named, no typo.
• No security rule has been added or modified since the SSO switch
• All apps have been exported and reimported but still failing identically on their respective monitor_apps_REST_* connections.
• Owner is INTERNAL\sa_repository (default, unchanged).
• Connection string uses the default pattern: provider=QvRestConnector.exe;url=https://localhost/qrs/license/useraccesstype/full;...;authSchema=ntlm;...
• Tested with an explicit port on the URL (:4243) — same error.
• Checked virtual proxies: we have Central Proxy (Default) (prefix mgmt, Authentication method = Ticket, Windows authentication pattern = Windows, this field is grayed out/system-managed) and Entra ID (SAML, no prefix). The default proxy already natively supports the Windows authentication pattern fallback, so it doesn't look like a virtual proxy/NTLM config issue.
• Temporarily created a dedicated virtual proxy (Windows-only, separate prefix) to isolate REST/API traffic from the SSO flow — same "Connection not found" error persisted, so we rolled it back.

Has anyone met this ? if you could help please

BR,

Hamid

Hello @hamid 

It seems to be a DataConnection access issue. Can you confirm that the service account (or the account running it) can read the data connections?
