Thank you very much . i have 2 doubts, i) if installed .net 8 future if i wanted to upgrade to .net 9 whethere reinstall .net required ii) if letsencrypt expired after 3 months it will auto renew,, Waiting for your reply
1. For upgrade, yes, you need to install .NET 9 on EC2. 2. Since we are also installing certbot, your certificate will be automatically renewed as soon as it reaches near expiry.
I have assigned IAM role with AmazonSSMManagedInstanceCore policy but still getting error of SSM Agent is not online and getting connect button as disabeld.
