SEC 5.3 Windows Event ID 16389 - Updates cannot be downloaded

Question

Installed SEC 5.3, Updates are not retrieved, therefore CIDs not filled and clients cannot update.

Windows EventID 16389 shown (Failed to read customer file content.)

Subscription is working with a standalone installation (same machine, different machine, tested all).

Re-Installed already, deleted DB, still the same.

Any thoughts?

It is SOLVED! :) :) :) The reason was the Gateway-AV from the hardware firewall blocking the download because it is containing virus signatures (Dell Sonicwall TZ series). Dumb me not to check this, but I was relying to an similar setup (same components) where it worked without adapting the Gateway-AV. So learned again, do not rely on experiences made. (I know, an appliance from Sophos would not have this issue, but we were fine with Dell also but will check Sophos appliances in the future definitely). A very very big Thank you to Mr. Wohlfahrt and Mr. Grunow from German Support team for their excellent Support, checking really everything with me together, had a patience that I was starting to miss and gave the final hint regarding the GAV. Superb Job!!! Thanks all again, I know why our recommanedations are going to out to Sophos products. Many many thanks! :-) :57182
