I have installed YugaByte and created a local cluster in one AWS EC2 (RHEL 8) machine by following [this](https://docs.yugabyte.com/preview/quick-start/) tutorial. The yugabyte is running as below:

[![enter image description here](https://canada1.discourse-cdn.com/flex027/uploads/yugabyte/original/1X/6bb792eee53aeb882d02f6159ea6a70204d0a2f8.png)](https://i.sstatic.net/QSCYJpcn.png)

The IP Address of the AWS EC2 machine is: 10.10.23.34

Now, I want to connect to the database using pgAdmin which is installed in my Windows machine and found that the server could be not reached.

I tried to run the yugabyte server with **–advertise\_address** flag but still could not connect with pgAdmin.

```
 ./bin/yugabyted start --advertise_address=10.10.23.34

```

I have tried with --listen flag but still could not connect.

> ./bin/yugabyted start --listen 0.0.0.0

How to change the listen address such as to any network so that the connection can be made to the yugabyte ysql server from the outside?

Hi @setu1421

Did you read my reply on your stackoverflow post [database - How to connect to YugaByte local cluster from PgAdmin - Stack Overflow](https://stackoverflow.com/questions/78669572/how-to-connect-to-yugabyte-local-cluster-from-pgadmin)?

Have you made sure a firewall isn’t blocking the access to your server from outside?

Did you also try with psql or ysqlsh?

What is 10.10.23.34 - the public or local address? The local one is on the VPC and is the one you put in ‘advertise\_address’. The public one exposes it through NAT and is the one you use from your pgAdmin client.  
You can check those addresses from the EC2 VM with:

```auto
grep ipv4s /run/cloud-init/instance-data.json

```
