Unauthorized alerts + timezone jump after Save (v26.2.4 → latest)

[seh2000]

Hi,
Maybe I overlooked something or did something wrong when upgrading from v26.2.4, but I’ve noticed a few behaviours that seem unusual. Everything works fine once the system settles, but I wanted to share these observations in case they are helpful.

1. Unauthorized alerts after pressing Save
   Whenever I press Save on the Settings page, I consistently get 10–20 “Unauthorized access attempt” alerts.
   They appear exactly every 10 seconds for about 1–2 minutes, then stop completely.

During normal operation (outside of saving settings), I get zero unauthorized alerts.

2. Timezone temporarily jumps forward
   Immediately after pressing Save, the displayed time jumps forward by 1 hour.
   After about a minute, it snaps back to the correct time.

This only happens during the reload triggered by saving settings.

3. Plugin engine briefly uses a stale token
   During the 1–2 minutes after saving settings, the scheduler runs jobs every 10 seconds, but they fail with “Unauthorized” until the token refreshes.
   After that, everything works normally.

4. UniFi API works perfectly once the reload storm settles
   After the initial reload, UniFi API successfully imports all devices across all VLANs.
   No issues once the system stabilizes.

5. UI sometimes shows a spinner due to PHP warnings
   Occasionally, the Settings page shows a spinner until the PHP warnings stop.
   This seems related to the reload sequence.

Active Plugins
Core / Mandatory:
UI, WORKFLOWS, SYNC, SETPWD, NTFPRCS, CUSTPROP

Maintenance:
CSVBCKP, DBCLNP, MAINT, VNDRPDT

Monitoring:
INTRNT, UNIFIAPI

Disabled:
SMTP, Network Scan (all entries removed — UniFi API used instead)

Environment:
Raspberry Pi 4B
Docker install
Upgraded from v26.2.4
UniFi UCG router with multiple VLANs
UniFi API enabled
Network Scan disabled

Everything works fine after the reload finishes — no unauthorized alerts, no time drift, and UniFi API imports all devices correctly.
Just wanted to share these observations in case they help with debugging or future releases.

Thanks again for all your work on this project.

Regards,
