Auto update Failed

Question

Hi all, 
 
 I have some sophos endpoint and protection problem, the client cant download the antivirus database. 
 The error message " Download of Windows Cloud Next Gen failed from server http://dci.sophosupd.com/cloudupdate . " 
 It happened from 12 Oct 2015 until now? 
 Anyone have a same problem? 
 
 Regards, 
 
 Arthur

Hi Dave, 
 Our working solution was deactivating the Tamper-Protection per failed client. Then just re-run the Setup (Login-Script / Remote-Install Tools like "PDQ Deploy" or manually) and about 30 Minutes later the Client should be working normal again. 
 We didn't always need restarts of the Clients, some just went back to normal after those steps. 
 Now, as far as my understanding goes, the Tamper-Protection protects any RegKeys and Files from being changed. What happens here is according to the Support that the Tamper-Protection is activated before the Installation is finished, in this case a Software-Update Installation. Sure someone might think this looks like the Software protects itself of being updated - but who am I to judge this :-). 
 Let me know if this helped you, I might now a few other tricks.

It seems like caching on the UTM is the issue... 
 Create an exception for caching, or a transparant proxy exception based on destination or disable this option: 
 
 In the case Sophos UTM is used as proxy one of the above options will solve your problem.
