java war file not starting

Before the emergency maintenance, things were working fine.

After that, the server is not starting up. I dont see any error msg too. Here are the commands I try.

nohup ./sniper-0.0.1-SNAPSHOT.war -Xms1024m -Xmx1024m -Xss256k | multilog t s10000000 n15 '!tai64nlocal' /home/jbalaji/sniper/log &

and then

./sniper-0.0.1-SNAPSHOT.war -Xms1024m -Xmx1024m -Xss256k

both these attempts give the following logs. But the webapp is not accessible from browser.

linode support suggested "sudo ufw allow 8080". That is not helpful.

Here is the log I get running the war.

@400000005b608c880346f764 2018-07-31 16:21:18.044 INFO 13754 --- [ main] com.neemshade.sniper.SniperApp : Starting SniperApp on ubuntu with PID 13754 (/home/jbalaji/sniper/sniper-0.0.1-SNAPSHOT.war started by jbalaji in /home/jbalaji/sniper)

Any help appreciated.
