Hi rePost-User-5598008, could you update your post with more network information?
From the first couple lines we can see your server received a time out in port 443.
Is your instance connected to the internet? If not, do you mind trying AWS Knowledge Center - EC2 Update YUM without internet ?
Have you checked the Security Groups rules for this specific instance?
Can you reach any other endpoint?
- telnet amazonlinux-2-repos-ap-south-1.s3.dualstack.ap-south-1.amazonaws.com 443 (should show Connected)
- telnet amazon.com 443( should show Connected)
