When we cannot restart the Bastion Reverse Proxy service but we want to change the LAC Filter log level do the following:

  • In the Admin Portal under 'Support & Maintenance' navigate to 'Logs and Settings'. Take note of 'Lac Log Level URL Update' value:

fe.china.agat.world/updatelacloglevels-4046
meet.china.agat.world/updatelacloglevels-4046

  • Add a new record forwarding traffic of the relevant host that's published in the channel, to localhost, AKA as 127.0.0.1:


  • A successful update should look like:
