Hello,

To resolve the issue of not being able to connect to your EC2 instance via RDP, follow these steps:

Check Security Group Rules:

• Ensure that the security group associated with your EC2 instance allows inbound traffic on port 3389 (RDP).
• Go to the EC2 Dashboard, select your instance, click on the Security tab, and then click on the Security Groups.
• Edit the inbound rules to add a rule for RDP (port 3389) if it doesn't already exist.

Verify Network ACLs:

• Ensure that the Network ACLs associated with your subnet allow inbound and outbound traffic on port 3389.
• Go to the VPC Dashboard, select Network ACLs, and check the rules for the subnet your instance is in.

Check Route Table:

• Make sure your instance is in a public subnet and that the route table has a route to an Internet Gateway (IGW).
• Go to the VPC Dashboard, select Route Tables, and verify that there is a route to the IGW.

Update RDP Client:

• Ensure you are using the latest version of the Microsoft RDP client.

Temporary Fix - Disable Clipboard Sharing:

• In the RDP client settings, disable clipboard sharing as it can sometimes cause issues.

Connect Using RDP:

• Open your RDP client.
• Enter the public IP address of your EC2 instance.
• Connect using port 3389.

Thanks everyone for the answers. It seems like it was an intermittent issue with wifi or my laptop. When I changed the wifi and restarted my laptop, it started working and now its working on my original wifi too.
