I am trying to setup access point on one computer and connect from another. Here is access point config (/etc/NetworkManager/system-connections/Hotspot.nmconnection):

[connection]
id=Hotspot
uuid=590dd05e-61eb-41e0-aa4f-b838c5675d77
type=wifi
autoconnect=false
interface-name=wlan0
timestamp=1675612177

[wifi]
band=a
channel=149
mode=ap
ssid=MyAccessPoint_5G

[wifi-security]
auth-alg=open
group=ccmp;
key-mgmt=wpa-psk
pairwise=ccmp;
proto=rsn;
psk=SuperSecret

[ipv4]
method=shared

[ipv6]
addr-gen-mode=stable-privacy
method=ignore

[proxy]

This config was created by

nmcli wifi hotspot ifname wlan0 ssid MyAccessPoint_5G password SuperSecret

On another computer (notebook) I am trying to connect to this hotspot using nm-applet. It tries for several seconds and fails, asking for password again.

Here is entry that it creates at (/etc/NetworkManager/system-connections/MyAccessPoint_5G.nmconnection)

[connection]
id=MyAccessPoint_5G
uuid=0a595f1c-925c-4904-861e-a96e21fbad24

key-mgmt=wpa-psk
psk=SuperSecret

[ipv4]

Here are logs from journal:

I created a simple config using wpa_passphrase:

network={
    ssid="MyAccessPoint_5G"
    #psk="SuperSecret"
    psk=8c2193dd5c26d1ce18553fdd17e3b1a93af3650f5d1fecaabf7efe2f4c162122
}

And when I start wpa_supplicant by hand it connects without problem.

$ sudo wpa_supplicant -cmyap.conf -iwlp5s0

The problem solved, once I change proto to wpa. By default, Hotspot was created with proto set to rsn.

There was no setting for proto in NetworkManager configuration, I've figured it from hotspot logs:

I've added proto wpa and all worked:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
