It has happened to me that when I force it by installing Docker and some Next.js containers, I can't access it via SSH, but it's due to the heavy load I'm putting on itHello there, I have few questions about ec2 instance in aws. I have created a free tier ec2 instance and installed apache server. And i used to connect with ssh but sometimes server is unresponsive and not connecting to ssh. is any alternative for server with free tier or should i need to upgrade the server?
