How To Fix ‘Took Too Long to Respond’ Error on Ubuntu Server?

Ubuntu 13

If you’re running a service on an Ubuntu server and you encounter the error “This site can’t be reached. Took too long to respond”, it can be quite frustrating. This error is usually an indication of a network or configuration problem. In this article, we will explore several potential solutions to this issue.

Check the Server’s Firewall Settings

The first step in diagnosing the problem is to check the firewall settings on your Ubuntu server. The firewall may be blocking the necessary ports for your service to communicate with the outside world.

To check the status of the firewall, you can use the ufw command:

sudo ufw status

This command will list all the current rules in the firewall. If the necessary port (for example, port 8081) is not open, you can open it with the following command:

sudo ufw allow 8081

This command tells the firewall to allow all incoming traffic on port 8081. Replace ‘8081’ with the port number your service is using.

Verify the Service is Running

Next, you should verify that the service you are trying to access is running on the server. You can use the systemctl command to check the status of the service:

systemctl status your_service

Replace ‘your_service’ with the name of your service. If the service is not running, you can start it with the following command:

systemctl start your_service

Check Network Connectivity

If the firewall settings and service status are correct, the next step is to check the network connectivity of your Ubuntu server. You can use the ping command to test the connectivity:

ping google.com

This command sends a network request to google.com and displays the response time. If you do not receive a response, there may be a problem with your server’s internet connection. In this case, you should contact your network administrator or internet service provider.

Check DNS Settings

Another common cause of the “Took too long to respond” error is incorrect DNS settings. If you are accessing the service using a domain name, make sure that the DNS settings are correctly configured.

You can check the current DNS settings with the following command:

cat /etc/resolv.conf

This command displays the content of the resolv.conf file, which contains the DNS servers that your server is using. If the DNS servers are not correct, you can change them by editing this file.

Clear Browser Cache

If you are accessing the service from a web browser, the problem may be caused by caching issues. In this case, clearing the browser cache can help. The process to clear the cache varies between different browsers, but it is usually found in the settings or history menu.

Check for IPv4/IPv6 Compatibility

Finally, if you are trying to reach an IPv4 address on a DSLite-type connection, this may cause issues. Make sure that your network configuration supports both IPv4 and IPv6.

In conclusion, the “Took too long to respond” error can be caused by various issues, from firewall settings to DNS configuration. By following the steps in this article, you should be able to diagnose and fix the problem. If you are still experiencing issues, provide more specific details about your setup and any error messages you receive for further assistance.
