Failed to download patches. Error code 12

Hi

When we try to download patches using Landesk, it fails with next error message in vulscan.log:

Fri, 17 Feb 2017 14:24:39 Download failed unable to get path, error code: 12 file: http://landesk_server/LDLogon/patch/INTL/Citrix/CitrixReceiver4.6.exe

I have tried with diferent patches, and error is the same.

If we try to download patches accesing URL http://landesk_server/LDLogon/patch/INTL/Citrix/CitrixReceiver4.6.exe , we can do it with no problems.

Any ideas?

Thanks in advance

Regards
