Download of WindowsCloudNextGen failed from server http:∕∕dci.sophosupd.com.

Hello,

I get this error message from all computers running in an office, and also on the server, where I have direct access to;

- I can ping all sophos update locations, directly visiting gives "success" message

- I deleted the auto update Cache, as of
Sophos Endpoint Self Help: Update then reinitiated an update, SophosUpdate.log the contained this:

https://pastebin.com/a0ENj129

 

- directly entering a .dat location in Browser gives a 404

for example:

https://dci.sophosupd.com/v3/d/45/d45972bff24b15b7a3e33f97ca619c39fd84712757a326c22f2c3b0636a17ebc.dat

but I also get  this 404 on my local browser, so it seems the files sophos autoupdate is trying to pull do not exist at all...

 

installed Sophos versions:

Last (successful) Agent Update:

  • Hello  

     

    Any traffic inspection from the update IP/URLs can cause issues with an install/update (due to checksums being altered, holding the update files for too long, etc).
     
    It is not uncommon to see several devices on the same network update correctly and have others fail to update due to a firewall configuration, as each endpoint may be looking to a different IP/URL for its updates.
     
    Your firewall rules need to be checked to include all of the locations listed in this article.

    Please check carefully that the full list of IPs and Domains are white-listed and that no traffic from these locations are being scanned or otherwise held in any way by the firewall or other security appliance. For example, SonicWall or any other Firewall AV would need to have whitelisted Sophos locations/ports mentioned in the linked article above.
     
    These actions can equally affect the update or install process.
