FGT 60e + FoprtiAp problem with connecting Mobile devices

[adastraaero]

Hello every, here is my problem:

I have FGT 60E + FAP21d/FP221. Notebooks successfully coonects to WIFI and can browse internet, but a lot of mobile devices like iphones connects to wifi, but can't reach internet.

At FortiAP log filtered by client i saw this messages:

client-disconnected-by-wtp ============== Action client-disconnected-by-wtp Reason Disassociated because sending STA is leaving (or has left) BSS

I tryed this https://forum.fortinet.com/tm.aspx?m=142151 , but it didn't help.

diag debug reset
diag debug flow filter addr X.X.X.X (client IP)
diag debug flow show ip en
diag debug flow show func en
diag debug console time ena
diag debug ena
diag debug flow trace start 999
