0

When I try to access my websites lightsail servers on AWS or visitors try to access one of the websites, processes stay hanging forever and I get error message site cannot be reached and when I do windows diagnostics it says my computer configuration is fine but DNS server not responding. What could be the problem?

    Please provide more details. What is your Lightsail configuration (instance, OS, network, application, etc.)? Was it working ever ?

There are a few potential causes for this issue. One possibility is that the DNS server is not properly configured or is experiencing issues. Another possibility is that there is a problem with the network connection to the Lightsail server or the server itself. Additionally, it could be a problem with the firewall or security group settings in your AWS account. Without more information about your specific setup, it is difficult to provide a more specific diagnosis. It is recommend to check the Lightsail and AWS Console for any error or issues, also checking the DNS settings, connectivity to the server and firewall rules.

    Thank you Oleksil and Divyam. Apparently just tried accessing the servers now and I was able but visitors still can't access one of the websites. My operating system is Linus. I have two websites. The servers are both currently running. One is Nginx running on NodeJS(website accessible) and the second is Apache running on WordPress (not accessible). I just checked my AWS health dashboard and it reports no issues. The second website using WordPress application is still not accessible to visitors

If you have recurring periods of availability and performance issues, it most likely means your load is causing your host CPU to run in the burstable zone. A CPU may only run in its burstable zone for limited periods of time, meaning the instance can become less responsive if the load consistently requires the burst capacity. If that turns out to be the case, you will want to either spread the load across multiple instances, or consider using a larger instance.

Lightsail provides documentation on instance health metrics here: https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-viewing-instance-health-metrics

In particular, the cpu utilization may be of interest in this situation: https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-viewing-instance-health-metrics#cpu-utilization-zones

    Thank you Andy. This is rePost-User-2660604. Signed in as I AM User for convenience. It is not a recurring experience. Never had it and not significantly increased the content of my blog in the last 2 years save minor corrections here and there.

I'd like to express my appreciation to the contributors to this issue and the community as a whole. I rebooted the server concerned and the remaining problem which is that of website accessibility by visitors has been resolved
