Signature updates not working - ASA5520-SSM-10

[whiteford]

Hi,

I have a Cisco ASA5520-SSM-10.

My signature updates have stopped working, they try to update everyday at 5am. My current version is 367.0.

What steps can I take to fix this as it is very new to me.

Thanks

Last time I had this issue, I found it was our Websense box stopping the IPS from accessing the update URL.
