1. Verify the IP address of the hosting

If a null route is being experienced by the web hosting, the ERR_CONNECTION_CLOSED error might appear. The ping command is the easiest way to find out if the server is up and functioning.

A data packet will be sent over the network’s switch and router to the target host by using the ping command. To make sure the result is legitimate, the command often sends out four or five ping requests at once.

The device with the given address confirms that it is online by sending back a ping reply after receiving a data packet.

To ping an IP address on Windows, follow these steps:

1. Type anything into the taskbar’s search area to launch Command Prompt. As an alternative, enter cmd and hit Enter using the keyboard shortcut WIN + R.
2. To verify the IP address or domain name, enter the domain name and execute the ping command. Let’s say we want to ping 8.8.4.4.

3. Hit the Enter key. There will be four instances of the pong reply.

After the fourth reply, the ping statistics will be displayed on the command prompt.

To ping an IP address on macOS, take the following actions:

1. To access Terminal, type a query into the search window and click the Launchpad icon on the Dock. Alternatively, double-click Terminal after choosing Finder, and opening /Applications/Utilities.
2. To give an example, we’ll type ping 8.8.8.8.

3. Ctrl + C can be used to end the ping command. After the connection is closed, the ping data will be displayed.

To ping an IP address on Ubuntu, follow these steps:

1. Use the shortcut Ctrl + Alt + T to open Terminal. As an alternative, type Terminal into the Show Applications window that appears in the bottom-left corner of your screen.
2. To check an IP address, use the ping command after it.

3. To end the connection, press Ctrl + C. The ping statistics will then show.

Expert Advice
In Linux, you can edit the packets that the ping command transmits to the server. You can alter the interval or provide a fixed number of packets, for instance.

As an alternative, you may use online ping tools like DNSChecker, ping.eu, and PingTool.org to see how the website server is doing.

A ping reply from the host can indicate that the ERR_CONNECTION_CLOSED problem is causing the issue.

2. Examine the Resources for Hosting

If the resources allocated to your hosting are being exceeded, you may receive the ERR_CONNECTION_CLOSED error message. We advise regularly checking the CPU, RAM, processes, entry processes, inodes, and disk consumption to avoid this problem.

Keep in mind that the 503 Service Unavailable error message might also result from reaching the resource restrictions.

3. Speak with Help

Resolving the connection closed problem from the client side might be challenging since it arises on the server side. While there are techniques to attempt in that regard, most need some prior technical understanding.

Therefore, we advise getting in touch with your hosting or internet service provider for assistance if the previous fixes are unable to resolve ERR_CONNECTION_CLOSED on the website.
