Estou tentando hospedar um servidor SSL Apache2 no Ubuntu 16.04 no domínio mturk.bitasy.me, mas tenho motivos para acreditar que o servidor está mentindo para mim, pelo menos em algum lugar. Eu criei dois arquivos no diretório de ativação de sites, um para HTTP e outro para HTTPS. Eles são postados abaixo. Por alguma razão o http funciona bem (se você for ao site você pode ver que funciona) mas o https não carrega, não importa o que eu faça. Cheguei mesmo a mover o arquivo de configuração http e ter apenas o SSL configurado no servidor web, mas mesmo nesse caso o HTTP (de alguma forma) funciona e o SSL (de alguma forma) ainda não está sendo hospedado. Este é o caso mesmo que eu tenha removido completamente a linha Listen 80 do ports.conf e substituído por Listen 443. Estou certificando-me de reiniciar o servidor toda vez ( sudo service apache2 restart ) e quando eu executo ( apache2 -S ) o resultado é como segue. Ele literalmente me mostra que não está escutando a porta 80, mas essa é a única porta com o site aparecendo! Eu também colocarei o log de erros abaixo, não que algo útil esteja nele. Minha intuição diz que de alguma forma o servidor não está atualizando quando eu reiniciá-lo, mas a impressão -S apenas faz isso parecer impossível. Não é que haja, de alguma forma, dois servidores em execução, porque quando eu paro, o site HTTP fica realmente indisponível.

# A self-signed (snakeoil) certificate can be created by installing
# the ssl-cert package. See

# If both key and certificate are stored in the same file, only the
# SSLCertificateFile directive is needed.
SSLCertificateFile /home/ubuntu/site.crt
SSLCertificateKeyFile /home/ubuntu/mturkhost.key
# Server Certificate Chain:
# Point SSLCertificateChainFile at a file containing the
# concatenation of PEM encoded CA certificates which form the
# certificate chain for the server certificate. Alternatively
# the referenced file can be the same as SSLCertificateFile
# when the CA certificates are directly appended to the server
# certificate for convinience.
SSLCertificateChainFile /home/ubuntu/GandiStandardSSLCA2.pem
# Certificate Authority (CA):
# Set the CA certificate verification path where to find CA
# certificates for client authentication or alternatively one
# huge file containing all of them (file must be PEM encoded)
# Note: Inside SSLCACertificatePath you need hash symlinks
# to point to the certificate files. Use the provided
# Makefile to update the hash symlinks after changes.
#SSLCACertificatePath /etc/ssl/certs/
#SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt
# Certificate Revocation Lists (CRL):
# Set the CA revocation path where to find CA CRLs for client
# authentication or alternatively one huge file containing all
# of them (file must be PEM encoded)
# Note: Inside SSLCARevocationPath you need hash symlinks
# to point to the certificate files. Use the provided

# Client Authentication (Type):
# Client certificate verification type and depth. Types are
# none, optional, require and optional_no_ca. Depth is a
# number which specifies how deeply to verify the certificate
# issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth 10
# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This means that
# the standard Auth/DBMAuth methods can be used for access control. The
# user name is the 'one line' version of the client's X.509 certificate.
# Note that no password is obtained from the user. Every entry in the user
# file needs this password: 'xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related 'SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.

Como é geralmente o caso com a depuração, percebi o problema depois de horas sem sucesso, imediatamente depois de pedir ajuda.
Estou usando um servidor Amazon Lightsail, cujo firewall é configurado por padrão para aceitar apenas conexões nas portas 20 e 80 para SSH e HTTP. Eu precisava permitir manualmente as conexões SSL na porta 443.
