First of all, you have to look into your logs to find out what's 
going on.  In most cases, this is a symptom of another another 
problem, usually nginx workers being killed or crashed.  For 
example, last time similar symptoms were traced to OOM killer 
activity, see here:

Also it might be a good idea to upgrade to a newer nginx version, 
as 1.13.5 is somewhat old.  Most recent 1.13.x version is 1.13.10, 
see http://nginx.org/en/download.html.
