No route to host: 6 Fixes

Here are some cases where you aren’t able to reach the host.
You can fix these issues by following a few steps:
1) Use phone service
2) Look for a different server nearby
3) Pingback results from other websites
4) Try sending an email instead of using chat services like Discord and Teamspeak which may be down or hard to access due to network problems.

The “port 80: no route to host” is a problem that has been present for a while. Google has released 6 fixes to fix the issue.

Linux is, for the most part, a painless operating system to operate. However, no operating system is immune to networking problems, and Linux is no exception.

We’ll look at the “no route to host” issue in Linux, its causes, and how to repair it in this post.

When the network, server, or host you’re attempting to connect to isn’t responding, you’ll get this error. It might be a result of an inactive internet connection, poorly configured router profiles, or any number of other factors that prevent you from accessing the server you’re attempting to visit.

Here are six options for resolving the no route to host problem.

Examine your web connection.

To play Minecraft, you must have an active internet connection. If your internet connection is unreliable, you’re likely to miss out on important alerts. Whether you’re on WiFi, check to see if you have access to the internet and strong signals. If you’re using mobile data, make sure it’s turned on and that you have excellent network coverage.

Network or host configuration files that are incorrect

Linux defines various rules in a set of configuration files, which it then utilizes to connect to the internet, a dedicated host via the internet, or even your local network. Check that these files are in order and that outbound connections are enabled. At the very least, look at the following three files:

/etc /hosts.allow /etc /hosts.deny /etc /hosts.allow /etc /hosts.deny

Examine your offerings.

The most apparent factor is whether or not the service you’re attempting to connect to is up and functioning. Check the status of any external servers you’re attempting to connect to to determine whether they’re up and operating.

Whether you’re running your own server, use the systemctl command to check if the service is up and running. 

systemctl status [service name] sudo systemctl status [service name] sudo systemctl status [service

Examine the port.

If the service is up and running, the port you’re connecting to is most likely the next point of failure. As a security precaution, most services alter their default port to prevent intruders from spying in and inflicting harm. Make sure you’re using the correct port number.

If you’re using your server, try executing the following command with NMAP to see which port your service is listening on.

sudo nmap -sS [IP of your server]

---

IPTables should be checked.

Another explanation for the issue might be that IPTables is banning connections on the port the service is attempting to use. Examine if the service is permitted to pass across IPTables.

iptables -S sudo

DNS problems

You’re most certainly dealing with a DNS problem if you can ping your server’s IP address but not the domain name. In most circumstances, your PC will automatically get DNS information via DHCP, but if you’re utilizing static IP assignments, things may be different. 

Here’s how to manually configure your DNS.

Step 1: Open the resolved.conf file from the following directory.

/etc/systemd/

Step 2: Remove the comment from the DNS= line and replace it with your router’s default IP address.

Your DNS files will be at /etc/resolve.conf if you’re using OpenRC or another systemd equivalent. After you’ve modified the rules, reboot your network and computer.
