We get “ERR_CONNECTION_CLOSED” in the browser when connecting from certain ISPs but not from others. However,
- Ping is successful
- Traceroute and MTR are successful
- DNS propagation has been completed.
When the app is deployed on another cloud provider, it is accessible from all ISPs. This issue occurred only when deployed on DigitalOcean and only with ISPs mentioned above. Is there any other method of troubleshooting this?
The app is deployed using DigitalOcean’s Managed Kubernetes platform and exposed using loadbalancer. Also, the domain doesn’t appear on any of the common blacklists.
