Http loopback issue in WordPress

Dear people of WPMUDEV,

I wish you a very happy & healthy 2016!

My question is for a new website SociaalGeluk.nl where the BackupBuddy plugin gives this error:

HTTP Loopback Connections are not enabled on this server or are not functioning properly. You may encounter stalled, significantly delayed backups, or other difficulties.

I have granted you access to this server sociaalgeluk.nl, are there diagnostic tools I can use to isolate the issue causing this?

BackupBuddy indeed hangs on backup. I also use SnapShot but there are still some restore tricks I need BackupBuddy for.

Many thanks for your help!

Cheers.
