I have a problem on my Ubuntu server. When I try to ssh from that server to a second server, I get this error:federico@federico:~/.ssh$ ssh root@federicolivieri.noip.me -vvvOpenSSH_7.2p2 Ubuntu-4ubuntu1, OpenSSL 1.0.2g-fips  1 Mar 2016debug1: Reading configuration data /home/federico/.ssh/configdebug1: Reading configuration data /etc/ssh/ssh_configdebug1: /etc/ssh/ssh_config line 19: Applying options for *debug2: resolving federicolivieri.noip.me port 22debug2: ssh_connect_direct: needpriv 0debug1: Connecting to federicolivieri.noip.me [95.144.54.179] port 22.debug1: Connection established.debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_rsa type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_rsa-cert type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_dsa type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_dsa-cert type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_ecdsa type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_ecdsa-cert type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_ed25519 type -1debug1: key_load_public: No such file or directorydebug1: identity file /home/federico/.ssh/id_ed25519-cert type -1debug1: Enabling compatibility mode for protocol 2.0debug1: Local version string SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu1debug1: ssh_exchange_identification: <!DOCTYPE HTML PUBLIC -//IETF//DTD HTML 2.0//EN>debug1: ssh_exchange_identification: <html><head>debug1: ssh_exchange_identification: <title>400 Bad Request</title>debug1: ssh_exchange_identification: </head><body>debug1: ssh_exchange_identification: <h1>Bad Request</h1>debug1: ssh_exchange_identification: <p>Your browser sent a request that this server could not understand.<br />debug1: ssh_exchange_identification: </p>debug1: ssh_exchange_identification: <hr>debug1: ssh_exchange_identification: <address>Apache/2.4.10 (Raspbian) Server at 127.0.1.1 Port 80</address>debug1: ssh_exchange_identification: </body></html>ssh_exchange_identification: Connection closed by remote hostHowever I can see the id_rsa under /home/federico/.ssh/federico@federico:~/.ssh$ ls -ltotal 76-rw-r--r-- 1 federico federico  1265 Jun 29 14:10 config-rw-r--r-- 1 federico federico  3261 Jun 22 09:59 id_rsa-rw-r--r-- 1 federico federico   727 Jun 22 09:59 id_rsa.pub-rw-r--r-- 1 federico federico 11906 Jul 19 09:28 known_hosts.bak-rw-r--r-- 1 federico federico  9682 Jun 30 09:04 known_hosts.oldI research for that error but everyone suggest something different and those solutions didn't work for me.
