i had the same issue. My VM had dynamic memory and the setup was made for 16GB.
I tried to increase the memory on my VM following the link provided above but got the 404 message.
I got it fixed by setting a fixed ammount of 16364MB of memory and the nsserver.cfg to
-Xms8g -Xmx8g -XX:HeapDumpPath=../../nsdump.hprof -XX:+HeapDumpOnOutOfMemoryError -XX:MetaspaceSize=128m
then restart the service.
Hope it helps
