Moodle apache proxy

I'm having troubles setting up a moodle instance behind an apache proxy. Here's my apache front-end that proxies to the running server. NameVirtualHost www.example.com:443 <VirtualHost www.example.com:443> ProxyPreserveHost On ProxyRequests Off ServerName www.example.com ServerAlias www.example.com ProxyPass / http://192.168.1.101/ ProxyPassReverse / http://192.168.1.101/ SSLEngine on SSLCertificateFile /etc/ssl/crt/example.com.crt SSLCertificateKeyFile /etc/ssl/crt/example.com.key SSLCACertificatePath /etc/ssl/crt SSLCertificateChainFile /etc/ssl/crt/example.com.bundle.crt </VirtualHost> On the concrete server I've got. $CFG->wwwroot = 'http://192.168.1.101/classes'; And <VirtualHost 192.168.1.101:80> ServerAlias 192.168.1.101 ServerAdmin webmaster@localhost ServerName 192.168.1.101 DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost> The thing is that I keep getting that moodle is only accessible from 182.168.1.101 something is not quite matching the expected. I've been able to configure confluence and other platforms but moodle doesn't work. The concrete error is as follows. Incorrect access detected, this server may be accessed only through "http://192.168.1.101/classes" address, sorry. Please notify server administrator. Does anyone know what might be happening?
