Same jar file works fine in my localhost and windows server (temp dev env). But when I run the same jar on linux box (using putty for this) and throwing above error. App is deployed and I can open the front page. But couldn't get in, as, it is not connecting DB and not LDAP server while i was trying to login using ldap authentication. So I tried ping both postgresql server and also ldap server and I got response successfully. But cannot connect through app. Please advise!
Please note this is linux server is newly mounted and not sure if there is any thing that needs to be configured other than javaidk.
my application-dev.yml looks like below for data source
