Cockpit not available for remote access

I have installed Cockpit and started the service, but am only able to open a connection from a web browser running locally, pointed to the default path of 9090. Remote connections are abruptly terminated with no HTTP response code.

The application is listening on all interfaces, and I have made no changes to any firewall configuration after installing EOS.

How may I resolve the problem, to access the service remotely?

Well…that is probably the problem.

You need to open that port in the firewall.

There should be a GUI installed to manage firewalld.

I am not familiar with firewall configurations, since most default installations of a Linux OS would not block any connections by default.

I had checked for a ufw service, and not finding it, I conjectured that the system had no firewall configuration.

I disabled firewalld and am able to access the service.
