Is it possible to configure hostname instead IP at the MQTT server? I tried my homeassistant.local and I can get connected (Tasmota it's ok). And if I put the IP it works.

Yes Example: host: mqtt.example.com, port: 1883 Check your router, firewalls, ports, forwarding and antivirus for blocking .

>>21798145 It's everything OK, the router, etc.The weird it's because I can ping homeassistant.local, tasmota uses it, and other MQTT stuff I have.

.local is usually mDNS which is not supported. Check you router, it should assign standard dns hostname to it. For example, OpenWrt assigns homeasistant and homeasistant.lan.
