Vertica management console - actions see fast tasks not working

sarafumes

Hi I have installed vertica management console on a separate t2.2xlarge ec2-instance but when i have imported my database , Under the recent databases, under actions-->if i click See Fast tasks,

I am getting an error -
"subnet must not be blank"

i have installed aws cli and have did aws configure, i am unable to figure out the next steps or solve this error, the ec2-instance has a subnet, but i am still not sure why i am getting this error,
Anybody faced this issue, how did you solve?

Please Help!
