I'm trying to add a second router via 802.11s mesh to my main router following the manual in the wiki and the @onemarcfifty Video.
Unfortnuately my mesh doesn't come up 
I installed wpad-mesh-openssl Here is my config:
cat /etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0'
option band '2g'
option htmode 'HT20'
option channel '6'
option cell_density '0'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'none'
option disabled '1'
config wifi-device 'radio1'
option type 'mac80211'
option path '1e140000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0'
option band '5g'
option cell_density '0'
option channel '48'
option htmode 'VHT80'
config wifi-iface 'wifinet1'
option device 'radio0'
option mode 'mesh'
option encryption 'sae'
option mesh_id 'my-mesh'
option mesh_fwding '1'
option mesh_rssi_threshold '0'
option key 'test1234'
option network 'lan'
This is what logread says:

By coincidence the devices are exactly the same as in the video. TP-Link Archer C7v2 as the main device and a Xiaomi Mi4 Gigabit as a second one. Both with OpenWrt 22.03.2. I tried on 5GHz first, with and without encryption, but no difference.
Do you have an idea why the mesh interface doesn't come up?
