Dashlets not displaying

Hi - I recently upgraded to 4.4.0 and the dashlets are timing out and not displaying. The log files show  this error, any ideas?:

** Solved **

Firewall was blocking API calls.

Anyone know the port number we need to open for this?

In our case it turned out that our htaccess password protect on the admin directory was blocking it.

I had to specifically allow the server IP (we already had allow from localhost but that wasn't enough, apparently)
