• Approach 1: The most likely to be possible reason for this issue is that your IP must have been blacklisted. Could you please check if your Elastic IP is blacklisted. If yes, whitelist it and try to ssh again. You can use ' spamhaus.org ' for checking the blacklisted IP and whitelisting it again.
• Approach 2: Not recommended, but you can try changing the Elastic IP if the issue still persists.
