Droplet is unable to reach a domain


I am hosting an app on Centos 8.1 droplet that runs on Apache/PHP/MySQL. The issue I am seeing is that from time to time it is unable to communicate with a domain “” on port 443. When this happens, I can access this domain from my laptop so it looks like the issue is on Digitalocean side. I have also disabled SELinux on this droplet for now and yet still seeing the issue.

Hi @KDSys the application is using on port 443 to validate a key string (license identifier). The license validation process is proprietary so I couldn’t find a log file for it.

But what I see is our app stops working with an error message saying it is unable to contact this address and port.Once this happens, I try to ping that address from the droplet and it times out. At the same time I can ping it just fine from my laptop. Then after a few minutes the droplet also is able to reach the address. So it seems like something is causing the droplet to intermittently not being able to reach that address.

Hi @pbhamburkar,

Can you confirm something, is your application using (maybe an API) for something? If you are experiencing issues accessing it, you should be able to see them in the log. It’s not necessarily related to your Droplet but the connection between your Application and

Can you confirm, how are you able to pinpoint the issues with communication you’ve mentioned, is it from your command line or are you executing some script?
