Downloads fail after configuring LiveUpdate Administrator (LUA) to download Endpoint Protection (SEP) content. Scheduled downloads may fail immediately or a few minutes into the download job.
In the lua.application.log (default location: %programdata%\Symantec\LiveUpdate Administrator\Logs) one or more of the following errors will be present:

#1: Update the connection retry limit and maximum active connections:
#2: Split up download schedules by product (ie, 14.3, 14.3 RU2, and 14.3 RU3 all in individual download schedules):
