Neo4j service crashes seconds after starting

Node Link

Host OS: Linux with 8 GB of ram

I'm trying to run neo4j inside a windows VM with 2G Ram given to it, I'm using neo4j version 4.1.1

today i started my vm again and i found that the Neo4j service was running and could open localhost:7474 in the browser, but a minute after the server crashes and i find this error in my neo4j log file

The error seems to be a problem with the port and address, but they seem to work at first so thats probably not the problem

here is some of my

# Java Heap Size: by default the Java heap size is dynamically calculated based
# on available system resources. Uncomment these lines to set specific initial
# and maximum heap size.
dbms.memory.heap.initial_size=256m
dbms.memory.heap.max_size=1G

# The amount of memory to use for mapping the store files.
# The default page cache memory assumes the machine is dedicated to running
# Neo4j, and is heuristically set to 50% of RAM minus the Java heap size.
dbms.memory.pagecache.size=1G

 

i tried all different values of memory, doesn't make much of a difference

I also tried different ports (instead of 7474 and the bolt one) no difference.
