Issue Resolved

ERR_TOO_MANY_REDIRECTS — Fix Walkthrough

A redirect loop was triggered on fresh Docker container restarts. Here is exactly what happened and how it was fixed.

Root Cause: Redirect Loop

On fresh container restart, core_key was missing from DB. auth_check.php redirected to license_setup.php, which detected an active license and redirected back — infinite loop.

Fix: Auto Re-Verification

auth_check.php now detects when core_key is missing but a license key exists. It calls verifyLicenseWithPortal(force=true) to silently re-populate the key without any redirect.

Result: Self-Healing on Boot

Every container restart auto-recovers the core_key. No manual intervention needed. The HTTP chain is now: localhost:2266 → 302 → login.php → 200 OK.

HTTP Flow After Fix

localhost:2266 → 302 → login.php → 200 OK ✓. After login, the dashboard loads fully with license status active and all monitoring features enabled.

includes/auth_check.php — key fix

- if (empty($raw_key)) {
-     header('Location: license_setup.php'); exit;
- }
+ // Auto-recover: re-verify if license key exists but core_key is missing
+ if (empty($raw_key) && !empty(getAppLicenseKey())) {
+     verifyLicenseWithPortal(true); // force re-fetch core_key
+     $raw_key = decryptSensitiveValue(getAppSetting('core_key'));
+ }
