I changed my password, restarted the droplet and I couldnt start tomcat ever since, when I try to start tomcat if get “UnknownHostException”.
WHAT I tried so far:
I have changed my droplet name to beta.mydomainName.com
my /etc/hosts/ looks like;
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 18.104.22.168 beta.mydomainName.com ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
