Angular frontend using OAuth behind Nginx with a strict CSP.
What happens
What happens
Login succeeds at the provider but the callback page refuses a required script and remains blank.
What I have tried
What I have tried
Added the provider domain to connect-src without success.
I would appreciate advice on how to identify the root cause without risking existing data or configuration.

AI DIAGNOSTICS
Incident analysis
Most likely causes
The callback bundle or inline bootstrap violates script-src rather than connect-src. 85%
A recent software, firmware or configuration change is exposing an existing compatibility issue. 37%
Summary
The reported behaviour is consistent with the callback bundle or inline bootstrap violates script-src rather than connect-src. The safest next step is to verify that hypothesis with a reversible test before making permanent configuration changes.
Suggested Fixes
Verify the likely cause
Read the exact browser CSP violation, use nonce- or hash-based script authorization and avoid broad unsafe-inline exceptions.
Validate and monitor
Reproduce the issue once after the change, review relevant logs or metrics, and keep a rollback path until the system has remained stable.
