LHG2: second wifi client cannot connect

I have LHG2 (RBLHG-2nD) AP and setting up wifi network on it using WISP. Although I’ve activated license L4, only one wifi client can connect to it. Rebooted may times.
Thanks for help.

please run

/interface wireless config export hide-sensitive

and post output. make sure to scrub anything you care about by replacing it with ****

Mode ap-bridge?
I’ve attached screenshots of winbox.

What are the log messages within the AP-bridge, once the second client tries to connect and what messages do the clients get when unable to connect?
