[iwlwifi] ipv6 connection problem

Hello,

Due to ISP changes I was forced to use ipv6 on my re0 ethernet so I can
have a funcional internet.

Now I'm trying to get ipv6 on iwlwifi (AX201) with /etc/rc.conf:
---
wlans_iwlwifi0="wlan0"
create_args_wlan0="wlanmode sta regdomain ETSI country PT"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
ifconfig_wlan0="WPA SYNCDHCP"
rtsold_enable="YES"
---
but wpa_supplicant doesn't connect after trying for some seconds.

How do I obtain more details to help showing my problem?
I've tried "wpa_supplicant_flags="-f /var/log/wpa.log" without success.

Thanks,
