0curl: (7) Failed to connect to apache.mirrors.ionfish.org port 80: No route to host

Posted on June 26, 2021

I logged in as root user & followed this link

https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-16-04

for basic configuration of my server. When i tried to download tomcat using the command: curl -O http://apache.mirrors.ionfish.org/tomcat/tomcat-8/v8.5.5/bin/apache-tomcat-8.5.5.tar.gz

it always shows the message: 0curl: (7) Failed to connect to apache.mirrors.ionfish.org port 80: No route to host

I haven’t found any solution for overcoming this issue.

Hi @buddiesworkshop07,

You’ve disabled or haven’t enabled connections from your Droplet on port 80. If you are using UFW, you can use it to allow the connections like so:

sudo ufw allow out 80
sudo ufw allow 80

If you are using IPtables instead of UFW, you can try using the following:

sudo iptables -A INPUT -p tcp --dport 80 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
sudo iptables -A OUTPUT -p tcp --sport 80 -m conntrack --ctstate ESTABLISHED -j ACCEPT
sudo iptables -A OUTPUT -o eth0 -p tcp --dport 80 -j ACCEPT
