wpa_supplicant not connecting anymore to eduroam

since a few weeks (probably after a dist-upgrade) my machine can't connect anymore to 802.1x networks. I'm using Debian Buster with i3, but using nm-applet. I've also tryied to connect directly with wpa_supplicant but it doesn't work either. This is my configuration: [connection] id=eduroam uuid=a86d2f21-990c-4a55-b7e4-933ffcffe0cd type=wifi permissions=user:root:; [wifi] mac-address-blacklist= ssid=eduroam [wifi-security] group=ccmp;tkip; key-mgmt=wpa-eap pairwise=ccmp; proto=rsn; [802-1x] altsubject-matches=DNS:nps1.unitn.it;DNS:nps2.unitn.it;DNS:nps3.unitn.it; anonymous-identity= ca-cert=/root/.cat_installer/ca.pem eap=peap; identity=[removed] password=[secret] phase2-auth=mschapv2 [ipv4] dns-search= method=auto [ipv6] addr-gen-mode=stable-privacy dns-search= method=auto This is the output of syslog: wpa_supplicant: wlan0: CTRL-EVENT-SSID-REENABLED id=0 ssid="eduroam" wpa_supplicant: wlan0: SME: Trying to authenticate with 00:26:0b:ac:91:d2 (SSID='eduroam' freq=2412 MHz) wpa_supplicant: wlan0: Trying to associate with 00:26:0b:ac:91:d2 (SSID='eduroam' freq=2412 MHz) wpa_supplicant: wlan0: Associated with 00:26:0b:ac:91:d2 wpa_supplicant: wlan0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0 wpa_supplicant: wlan0: CTRL-EVENT-EAP-STARTED EAP authentication started wpa_supplicant: wlan0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=IT wpa_supplicant: wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=25 -> NAK wpa_supplicant: wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21 wpa_supplicant: wlan0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected wpa_supplicant: wlan0: CTRL-EVENT-DISCONNECTED bssid=00:26:0b:ac:91:d2 reason=4 locally_generated=1 wpa_supplicant: wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD wpa_supplicant: wlan0: SME: Trying to authenticate with 54:75:d0:3f:4d:2d (SSID='eduroam' freq=5200 MHz) wpa_supplicant: wlan0: Trying to associate with 54:75:d0:3f:4d:2d (SSID='eduroam' freq=5200 MHz) wpa_supplicant: wlan0: Associated with 54:75:d0:3f:4d:2d wpa_supplicant: wlan0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0 wpa_supplicant: wlan0: CTRL-EVENT-EAP-STARTED EAP authentication started wpa_supplicant: wlan0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=IT wpa_supplicant: wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=25 -> NAK wpa_supplicant: wlan0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21 wpa_supplicant: wlan0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected wpa_supplicant: wlan0: CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/CN=eduradius-dr-2018' hash=86fdb85978a8d3c9ba28e40f1f10415d49c0a595b8752556906d37ac9d1884fc wpa_supplicant: wlan0: CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/CN=eduradius-dr-2018' hash=86fdb85978a8d3c9ba28e40f1f10415d49c0a595b8752556906d37ac9d1884fc wpa_supplicant: wlan0: CTRL-EVENT-EAP-FAILURE EAP authentication failed wpa_supplicant: wlan0: Authentication with 54:75:d0:3f:4d:2d timed out. wpa_supplicant: wlan0: CTRL-EVENT-DISCONNECTED bssid=54:75:d0:3f:4d:2d reason=3 locally_generated=1 wpa_supplicant: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="eduroam" auth_failures=2 duration=23 reason=AUTH_FAILED wpa_supplicant: wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD Apart from waiting for an update what could I do?
