Endpoint failing to update

 Hi

I have a problem with Endpoint not updating and I need assistance troubleshooting the issue. I have found the following in the log, highlighted below. Proxy IP removed by me. I have no other working servers in the environment to test with.

Is this saying that the username/pwd I have for updates is no longer working?

I assume that the update is getting out through my proxy, using IE I can get to the http://dci.sophosupd.com site okay.
