Slzb-07 router mode how to re-pair to zigbee2mqtt

I updated the router firmware on the slzb-07 USB dongle. I’ve been using it as a repeater/router, not as a coordinator.

Because it was getting a low LQI, I decided to “Forget” the router on zigbee2mqtt thinking that it would just automatically connect. However, it doesn’t!

I was told to go to SMLIGHT web flasher (SMLIGHT FIRMWARE UPDATER) and hit the “reconnect router” button, but when I do, nothing happens. Nothing shows up on my zigbee2mqtt web interface after allowing devices to join.

Is there any other way for the device to go back into pairing mode?
