It's ubuntu so i installed a mosquitto once again and reflashed the esp with the new IP address. Now all i get on the ESP12 is</p>
<pre><code>Jan 31 19:26:23 mosquitto[6673]: New connection from ESP_IP
Jan 31 19:26:23 mosquitto[6673]: Socket read error on client (null), disconnecting.
</code></pre>
<p dir="auto">And on the UBUNTU server</p>
<pre><code>1454258121: New connection from ESP_IP.
1454258121: Invalid protocol "MQTT" in CONNECT from ESP_IP.
1454258121: Socket read error on client (null), disconnecting.
</code></pre>
<p dir="auto">Out of ideas here...</p>
