Hello tharun518,

thanks again - and sorry, I'm dense today. Simply test with http://dci.sophosupd.com - it should respond with

Sophos dci Site

Connection Successful

Anyway, apparently a connection can be established. It doesn't show whether AutoUpdate's request times out, receives a 404, some other error, or unexpected data. Looks more like an issue on the backend (provided it has worked before).

URL http://dci.sophosupd.com is working for me and getting the same page. The one I tried earlier was dci.sophosupd.com/update

Hello tharun518,

if it did work before (you still haven't answered this question [:)]) it's likely a transient issue with the CDN. If not a packet trace could give some hint. Dunno if AutoUpdate has an option to enable verbose logging - I'd have to look around but it'll take some time.

Before we was using managed sophos version. Just moved to standalone alone version 2 days back and issue started. So earlier clients were contacting our local server for updates. 

How do we resolve this if it is a CDN issue? Try for last 2 days to make this work. 

Hello tharun518,

two days is very likely not the CDN. How did you move to standalone? You uninstalled completely before installing SA, didn't you? Oh, BTW, and why the SA version, what's the benefit?
I don't manage SA installations (forgive the bad pun) so I don't have much experience with them. Won't rule out that some leftovers are the cause even though I don't really think so. Perhaps one of the newer debug logs contains some more information.
