Opened this issue 5 years ago · 0 comments

Hello all,

As per the exercise for AWS class on 5th August, to setup 3 servers : Webserver > Appserver > DBserver and using NACL allow inbound connections from web to app and then app to DB finally. I am having issues in connecting from Appserver to DBserver and getting below error.
Error :
ssh: connect to host 192.168.3.230 port 22: Connection timed out

CIDR IP
Webserver : 192.168.1.0/24
Appserver : 192.168.2.0/24
DBserver : 192.168.3.0/24

Also checked port 22 is open from security group

DBsubnet NACL :
