Eu estava enfrentando o mesmo problema, mas, felizmente, depois de investigar as configurações do apache , consegui resolver isso.
Aqui está o meu arquivo de configuração do apache, ou seja, 000-default.conf , que serve a página padrão em vez do meu aplicativo. Nota *: Os exemplos estão sendo mostrados abaixo com a ajuda da configuração do AP Apache.
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName 31.220.49.197
WSGIDaemonProcess ts threads=25
WSGIProcessGroup ts
Alias /static /home/email-validator/static
WSGIScriptAlias / /home/email-validator/index.wsgi
# Set access permission
<Directory />
Allow from all
Require all granted
</Directory>
</VirtualHost>
E depois de comentar a configuração padrão do virtualhost na porta 80 resolve o meu problema embora ainda estejamos recebendo os mesmos logs de erro:) .
isso significa comentar ou remover toda a seção padrão / primeiro <VirtualHost *:80>
resolverá o problema.
Atualmente, estou tendo o Ubuntu 14.4 e esse problema surgiu após a atualização de 12.4.
