avast eps client downloads partial file

My avast eps only downloads 83.8 MB of the file and then stops. This problem happens frequently. I am unsure how to clear up this problem, but I go onto the console and run all the jobs to clear unused files and update server definitions. At some point the download lets me download the complete file (323 MB my problem resolved overnight) but days to weeks later i run into the same issue.

this is the link i go to to download the client
http://avastserver:8731/Install.aspx?prod=EPS

console:
avast small office administration
program version: 1.3.3.42
database version: 1450

client:
program version: 8.0.1603

anyway to stop this from happening? or the steps that fix it?
