Hi could anyone please help, i am running two Ec2 instances under same security group, both were running ok, i just installed jenkins, docker on one instance and ran command ufw allow 8080 in one instance.
also i enabled thru sudo ufw allow OpenSSH and sudo ufw enable using putty.
I am now unable to connect the instance with all installations and also ssh port shows closed.
while the other instance with same security group port shows open and running properly in putty.
Please do help me someone. Thanks
