Hi,
I have the same problem with WPBackup 3.2.2 on WordPress 4.3.
Wordpress is hosted on a Root Server with Apache 2, PHP 5 and MySQL.
The Database-only Backup works fine.
“Der HTTP Antwort Test bekommt diesen Fehler “Connection timed out after 15000 milliseconds”Nicht erwartete HTTP Body: “
Can I post any debug information to the thread that helps you to localize the problem?
