EC2 server losses internet connection and application fails to send email, sms and even yum updates

I have 5 EC2 servers in the same VPC and all of a sudden yesterday, all of my applications started failing to send email and sms. So I tried doing git pull of my project it also timed out. Then tried to install telnet using yum that to failed with Time out. I have checked almost everything including Network ACLs, Security Groups, Subnets, Iptables, etc and everything is correct. I am not sure why is this happening. The weird thing is if I reboot the server once the internet comes for a brief amount of time and again it disconnects.

Attaching below are the errors I am facing:

Error while Generating the Tiny URL. Error: {"errno":-110,"code":"ETIMEDOUT","syscall":"connect","address":"XXX.XX.XXX.XX","port":443}


Error SendEmail UnknownEndpoint: Inaccessible host: `email.ap-south-1.amazonaws.com'. This service may not be available in the `ap-south-1' region.

Attaching screenshots of my Network ACLs, Security Groups, Subnets, and iptables:

Please help with what am I doing wrong or if is this an issue with AWS EC2? My goal is to make sure my application works without timeout and git and yum starts working.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
