Posted December 25, 2014

Hello! Recently I removed IPTables on my Centos 7 Droplet and since then I cannot access my server via SFTP only via the Droplet console… I understand that It has to be some sort of Centos 7 specific Firewall problem? Any suggestions to fix this problem Is much Appreciated… Thanks!

CentOS 7 uses firewalld to implement firewalling. To check if it is enabled, run:

sudo systemctl status firewalld

If you use the default port 22 for SSH connections, you can open that port by running:

sudo firewall-cmd --permanent --add-service=ssh
sudo firewall-cmd --reload
