Project is deployed on AWS 🎉

  1. Go check it live on :-
<your-public-ipv4-address-of-ec2>:<PORT>
#for example- 13.236.137.31:3000

  1. But you forgot to expose your port out to the world. For that my friend, we will have to edit the inbound rules in the security group of our EC2, in order to allow traffic from our particular port. To fix this, follow these quick steps:

    1. Go to "Security" and then "Security Groups."

    2. Edit the inbound rules.

    3. Add a rule for the specific port.

    4. Save the changes to allow traffic on that port.

  1. Repeat step 1. And booom.
