SSH to EC2 instance with RSA pem on private ip

Question

We have an  ec2 instance that has not been enabled for public ip. It is connected to a VPC, with  TGW peering.

SSH instance fails with Operation Timed out. error.

```
Authentication provider $SSH_SK_PROVIDER did not resolve; disabling
...
ssh: connect to host  port 22: Operation Timed out
```

Answer

Hello.

Since it is a timeout error, please check whether the required IP address is allowed in the inbound rules of the security group set on the EC2 destination.  
There is also a possibility that the network ACL set for the subnet is related.  
Also, are the appropriate routing settings in the Transit Gateway route table and subnet route table?
