Hello Everyone,
After installing my droplet (Ubuntu 18.04) I am trying to change the default ssh port (port 22), I tried several ports and on testing the connection times out, HYG what I tried so far:
- Changed the port in the file /etc/ssh/sshd_config
- Restarted the sshd service using systemctl restart sshd
- Also restarted the ssh service using systemctl restart ssh
- Tried ssh connecting from outside the droplet using Putty and from another droplet and in both cases the connection times out
- Tried ssh connecting from localhost and it works on the new port
- Checked the service status using (systemctl status sshd) & (systemctl status ssh) and both are active and listening on the correct port
- I also tried adding DO firewall from the console to add a custom port using the new one I added
Don’t know what else to try, can it be related to UFW and how to check/change this?
Thanks

Hello, @aymanroshdy2019
You can use telnet or nmap to see if the port is actually open and if you’re able to receive connections on it:
telnet IPADDRESS port
nmap IPADDRESS
Let us know how it goes.
Hello,
If the UFW is enabled you need to put the new port in allow list.
sudo ufw allow <NewPort> sudo ufw reload
