Sonoff B02-F local mode stops working after HA/SonoffLAN upgrade

[xriser]

Issue:
After upgrading Home Assistant (HA) and the SonoffLAN integration to the latest versions, the local mode functionality for my Sonoff B02-F bulbs stopped working. This was functioning correctly before the upgrade.

Steps Taken:

Reinstalled the integration.
Attempted to repair the bulbs multiple times.
Enabled debug logs.
Downgraded the SonoffLAN plugin from version 3.7.3, trying various configuration options (auto/cloud/local).
Observations:

Despite the attempts, local mode remained non-functional.
Upon downgrading to version 3.6.0 of the SonoffLAN plugin, local mode started working again immediately after restarting HA.
Attachments:

Debug logs from version 3.6.0 where local mode works:

Debug logs from version 3.7.3 where only cloud mode works:

Just want to confirm, the integration is NOT working if there is no wan connection on my side neither. Unfortunately I dont have any historical comparision thus I have found and installed the SonoffLan HACS integration yesterday.
I intend to use it for a Ewelink 8 channel relayboard (with duo PSF-B04 module), what i was unable to flash to Tasmota.
