Unable to login since a recent system upgrade

[Rawleenc]

Explain what happens

1. Trying to login
2. Cockpit tell me there was and unattended error during the connection and tell me to check logs with journalctl -u cockpit
3. There is nothing here but when checking journalctl -fb during the login attempt I get this :

Jan 07 21:12:15 localhost cockpit-session[xxx]: pam_ssh_add: Failed adding some keys
Jan 07 21:12:15 localhost systemd-logind[xxx]: New session 27 of user user.
Jan 07 21:12:15 localhost systemd[1]: Started Session 27 of User user.
Jan 07 21:12:15 localhost cockpit-session[xxx]: pam_unix(cockpit:session): session opened for user user(uid=1000) by user(uid=0)
Jan 07 21:12:15 localhost sudo[xxx]:      user : PWD=/ ; USER=root ; COMMAND=/bin/cockpit-bridge --privileged
Jan 07 21:12:15 localhost sudo[xxx]: pam_unix(sudo:session): session opened for user root(uid=0) by user(uid=1000)

Nevermind.

The issue was on the traefik side : https://github.com/traefik/traefik/releases/tag/v3.3.0
There is an issue with websocket upgrade on traefik 3.3.0 but there is a workaround in the release note.

Sorry for this.
