Не удалось настроить SSL на Tomcat 9 на AWS EC2

Я следую этому руководству по настройке ssl на моем Tomcat 9, размещенном на AWS EC2 (Ubuntu 16.04.5 LTS).

Версия: java-8-oracle, apache-tomcat-9.0.10

Ключ создан на /home/ubuntu:

ubuntu@ip-x-x-x-x:~$ sudo keytool -genkey -alias tomcat -keyalg RSA -keystore ./test
Enter keystore password:  
Re-enter new password: 
What is your first and last name?

What is the name of your City or Locality?
  [Unknown]:  City
What is the name of your State or Province?
  [Unknown]:  State
What is the two-letter country code for this unit?

  [no]:  yes

Enter key password for <tomcat>
    (RETURN if same as keystore password):  
Re-enter new password: 

Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore ./test -destkeystore ./test -deststoretype pkcs12".

Преобразовать ключ в PKCS12:

ubuntu@ip-x-x-x-x:~$ sudo keytool -importkeystore -srckeystore ./test -destkeystore ./test -deststoretype pkcs12
Enter source keystore password:  
Entry for alias tomcat successfully imported.
Import command completed:  1 entries successfully imported, 0 entries failed or cancelled

Warning:
Migrated "./test" to Non JKS/JCEKS. The JKS keystore is backed up as "./test.old".

ubuntu@ip-x-x-x-x:~$ keytool -list -keystore ./test
Enter keystore password:  
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

tomcat, Aug 5, 2018, PrivateKeyEntry, 
Certificate fingerprint (SHA1): E7:F9:46:D4:F8:91:E6:A9:68:54:98:6C:22:CF:EE:6D:C5:6A:FF:17

изменять /opt/tomcat/conf/server.xml:

<Connector port="80" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="443" />

<Connector SSLEnabled="true" acceptCount="100" clientAuth="false"
    disableUploadTimeout="true" enableLookups="false" maxThreads="25"
    port="443" keystoreFile="/home/ubuntu/test" keystorePass="password"
    protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https"
    secure="true" sslProtocol="TLS" />

Включить брандмауэр:

ubuntu@ip-x-x-x-x:~$ sudo ufw status
