Can't connect to wifi anymore

I use NetworkManager to connect to my school's wifi, which on my phone asks for username and password. A few months ago I was able to set up a config that would work, but this config no longer works and I have no idea why.
This is my current configuration using nm-connection-editor:

[b]Wi-Fi[/b]
SSID: Alumnos
Mode: Client
Band: Automatic

[b]Wi-Fi Security[/b]
Security: WPA/WPA2 Enterprise
Authentication: Tunneled TLS
Inner Authentication: MSCHAPv2 (no EAP)
Username: [my username]
Password: [my password]

All the other settings are blank

When running 

nmcli dev wifi connect Alumnos

I get:

Error: Failed to add/activate new connection: Failed to determine AP security information

This is almost instant, which makes me think there's something obviously wrong with how I have it configured, or some setting I have, but I couldn't find anything on this forum that helped or on the internet
I can still connect to my mobile hotspot, which makes me think it's something I've messed up in the wireless configuration. I also have a wpa_supplicant config:

/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/run/wpa_supplicant
update_config=1

network={
	ssid="Alumnos"
	psk="password"
	key_mgmt=WPA-EAP
	eap=PEAP
	identity="********"
	password="*******"
	phase1="peaplabel=0"
	phase2="auth=MSCHAPV2"
	mesh_fwding=1
}

I don't think it's relevant because I disabled wpa_supplicant.service a long time ago, but it's something that might help, I suppose

Re: Can't connect to wifi anymore

NM will still use wpa_supplicant (unless you configured it to use iwd), please post a complete system journal for a boot after failing to connect to the eduroam AP: 

sudo journalctl -b | curl -F 'f:1=<-' ix.io

sudo journalctl -b | curl -F 'f:1=<-' ix.io

is:

(I think what you're looking for is when you Ctrl + F "Alumnos")

Also, the connection is not eduroam

Following the result posted at the end of this just made my device show up as "unavailable" when running 

nmcli dev

I reverted the changes, but think it might have something to do with them using 

wlp3s0

in the ExecStart line, where I think mine could be different, hence it not working. Any ideas as to this?

Re: Can't connect to wifi anymore

Your device name is "wlan0"
The journal has

Jul 08 13:42:23 TheMysteryMachine sudo[595]:  nucieda : TTY=pts/0 ; PWD=/home/nucieda ; USER=root ; COMMAND=/usr/bin/nmcli dev wifi connect Alumnos

but the only SSID ever showing up is "Banana" and it took you about 1s to connect to that.
There's no log of any attempt by NM to connect to "Alumnos", but only 

Jul 08 13:42:23 TheMysteryMachine NetworkManager[360]: <info>  [1688816543.4014] audit: op="connection-add-activate" pid=596 uid=0 result="fail" reason="Failed to determine AP security information"

nor any SSL errors.
I'd say you're not even using the existing profile? What if you don't "sudo" nmcli?

Re: Can't connect to wifi anymore

If I don't "sudo" I get the same error message:

[nucieda@TheMysteryMachine ~]$ nmcli dev wifi connect Alumnos

Re: Can't connect to wifi anymore

Does the AP show up in a scan?
Are there any documentations authentication protocol privided by your school?

School doesn't provide anything, unfortunately. The AP shows up:

Re: Can't connect to wifi anymore

Did/does the school issue a certificate for the authentication?
Edit: and ideally post an old journal where you successfully connected to the school's AP

School provides nothing, I asked about it.
I have no idea how I could even get an old journal like that

"sudo journalctl -b -10" is the journal for 10 boots ago.
