Certains sites inaccessibles ...

Bonjour,

voilà le problème que je rencontre : deux sites sont inaccessibles, que ce soit sur mon portable ou sur le fixe ( tous deux reliés à une livebox.) Le site fr.grepolis.com et le site de téléchargement de java https://javadl.oracle.com/

Les autres sites ne posent aucuns problèmes de connexion.

Message d'erreur : Le serveur à l'adresse fr.grepolis.com met trop de temps à répondre.

Chose étrange sur https://fr.grepolis.com/

J'ai :
Placeholder page
The owner of this web site has not put up any web pages yet. Please come back later.
You should replace this page with your own web pages as soon as possible.

Unless you changed its configuration, your new server is configured as follows:

* Configuration files can be found in /etc/lighttpd. Please read /etc/lighttpd/conf-available/README file.
* The DocumentRoot, which is the directory under which all your HTML files should exist, is set to /var/www.
* CGI scripts are looked for in /usr/lib/cgi-bin, which is where Debian packages will place their scripts. You can enable cgi module by using command "lighty-enable-mod cgi".
* Log files are placed in /var/log/lighttpd, and will be rotated weekly. The frequency of rotation can be easily changed by editing /etc/logrotate.d/lighttpd.
* The default directory index is index.html, meaning that requests for a directory /foo/bar/ will give the contents of the file /var/www/foo/bar/index.html if it exists (assuming that /var/www is your DocumentRoot).
* You can enable user directories by using command "lighty-enable-mod userdir"

J'ai un antivirus Avira.

J'ai désactivé le pare-feu.

Je ne sais pas trop où chercher. Auriez-vous quelques idées ?

D'avance merci pour votre aide.
