Hi,

It looks like 'localhost' is only resolving to ::1 (IPv6) on your machine.
Is your MQTT-SN broker only listening on IPv4?

Can you try connecting to 127.0.0.1 instead?

Hi, using 127.0.0.1 works correctly. The sw using docker (using host option in docker-compose), use my etc hosts, of CentOS, the default: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 Using no host option same behavihour. It listen as default also, ipv6 is used or ipv4 as default (netstat -putadon) Also, defining one IP for my host in my /etc/hosts, example: myip myhostname And connecting using myhostname, then works correctly (using the client mqtt-sn-tools). Summarizing: Using: dns, 127.0.0.1, and one /etc/hosts works Using localhost then no. Regards, Cesar Jorge El lun., 20 dic. 2021 14:33, Nicholas Humfrey ***@***.***> escribió:
