Okay. I don’t know what could be wrong with the webserver either. You can change the loglevel in /etc/defaults/urbackup_srv to debug. Then the webserver will log every access into /var/log/urbackup.log.
UrBackup uses FastCGI. This is a extension of CGI for long running processes. This literally means that you just have to point /urbackup/x to backupserver:55413 and everything should be fine… The examples for webservers with php etc. are much to complicated as there the webserver has to start multiple instances of PHP (because every instance can only handle on request at a time) and you have to associate the specific file extension with these instances (For UrBackup it’s only one file).
location /urbackup/x {
include /etc/nginx/fascgi_params;
fastcgi_pass 127.0.0.1:55413;
}
worked for me. (You have to symlink/copy the urbackup files from …/urbackup/www to /urbackup as well).
Hope you get it to work!
