Fetching Text File Not Consistent

Hi,

I recently started having the problem with my script where I would fetch a text file which has list of IP address in the command format (add list=Blacklist address=0.0.0.0 comment=X) so the problem is this when I run the script it seems to only download about 3/4 of the text file basically a different amount of the text file every time (see the file sizes below when I run the script)

blacklist.rsc 240.0KiB sep/22/2016 10:29:11
blacklist.rsc 278.4KiB sep/22/2016 10:45:06
blacklist.rsc 272.0KiB sep/22/2016 10:45:32

Script:
/tool fetch url=“https://ADDRESS/blacklist.rsc” mode=https; :log info “Downloaded blacklist.rsc”;

So if anyone knows if there is a line limit possibly with RSC files or problem with fetching text files/my script like timeouts your help will be appreciated.

Thanks

Anthony
