then after that It tried launching ubuntu instance and do it manually but that to I couldn't access, same issue persist.

Accepted Answer

Did you check if one of security group attached your EC2 instance allows TCP port 22 to your IP or All Traffic.

Is your instance is deployed in public subnet, could you please make sure that the subnet has [internet gateway](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html) attached to it's route table, otherwise resources inside that subnet can't reach to internet and hence that subnet is not public. Please double check the routes.

[AWS Documentation](https://docs.aws.amazon.com/en_us/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html) covers almost all the possible causes, which could prevent accessing the instance.

Hope you find this information helpful.
