I cannot access my Windows EC2 Instance

Question

My Instance has been giving me issues since I launched it. Sometimes I get access to the instance, but most times I don't. I have to either edit Route or Inbound and outbound rules before getting access. Most times the instance is so slow I can barely do a thing. Currently, the instance takes forever to open and when it does, it opens a blank page. A few minutes after, I get an error message "0xf". When I reboot my Instance and try to access it, I get this error message "We couldn't connect to the remote PC because the session couldn't be established in time. If this keeps happening, contact your network administrator for assistance."
Please I need help with this.

Please try the following AWS official documentation for troubleshooting if you have not already done so. [1]

[1] Troubleshoot connecting to your Windows instance - Amazon Elastic Compute Cloud  
https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/troubleshoot-connect-windows-instance.html

There was also a QA about the same error, which I hope will be helpful. [2]
