Hi, I am not able to manage to open port 1883 on an ubuntu droplet at digitalocean.
I activated UFW and then open port 1883, but a port scan does not succeed….
Any Ideas what could be wrong….
this is the answer of ufw status:

1883 ALLOW Anywhere

Hello Joachim,
Did you run this command?
Update the firewall to allow connections to port 8883.
sudo ufw allow 8883_ _ _ _ _ _ _
