I've given up, don't have time to investigate any further & need to get things running. Currently mid-migration to ERAS v6 & v6 clients, which is a whole other exciting adventure of broken services and complications.

Upgraded to ERAS 5.3.3 and purged the server updfiles and mirror folder contents - this did not fix the stuck clients. On the stuck clients I then purged: * C:\ProgramData\ESET\ESET Endpoint Antivirus\Updfiles\*.* * C:\Program Files\ESET\ESET Endpoint Antivirus\em0**_32/64.dat and they successfully updated to latest signature. Waiting to see if the problem continues to recur. Edit: Upgrading to ERAS 5.3.3 has not fixed it for us, we're continuing to see Win10 clients get stuck with "Error downloading the update".

Was also seeing this, 5.0.2254 clients updating against ERAS 5.2.26. Mostly Win10 machines, but with a couple of occurrences on Win7 clients. Started around 22.04.16. Did not fix it: * Clearing the ERAS update cache (from within UI) does not fix it. * Manually clearing: C:\ProgramData\ESET\ESET Remote Administrator\Server\updfiles\*.* C:\ProgramData\ESET\ESET Remote Administrator\Server\charon\*.* C:\ProgramData\ESET\ESET Remote Administrator\Server\mirror\*.* .. does not fix it. * Rebuilding the ERAS mirror does not fix it. * Pointing the stuck client directly at ESET update servers does not fix it. * Clearing the client update cache (from within UI) does not fix it. Did fix it (temporarily)- Purging the following client folder contents: * C:\ProgramData\ESET\ESET Endpoint Antivirus\Updfiles\*.* * C:\Program Files\ESET\ESET Endpoint Antivirus\em0**_32/64.dat .. but we saw the problem recur on some clients anywhere from 6 -24hrs later. The stuck clients seem to have successfully updated themselves to signature 13428 over the weekend though, so will see what happens..
