MQTT Connector not connecting (except the first one created)

[cocoaway]

LoraWan Server version: 0.7.0 Operating System: Ubuntu 18.04 LTS

Except the first MQTT connector all the others do not connect and do not detect non-existent brokers

I have created multiple MQTT connectors, but only one connects and communicates (the first one created) with the broker.

The others are active as status (green check) but do not transmit anything.

Each MQTT connector has a specific handler. Each connector has its own clientID, name and password. The Auth is Username + Password.

On the Status tab, in the Connections field, nothing appears, the same for the Alerts field.

The connecotr is enabled.

In the Handler Test button is grayed out, it cannot be clicked.

In the Connectors in Handler field the name of the connector appears and is clickable. It turns out to be Enabled.

The other MQTT connectors are not seen by the broker.

If I create a connector with a nonexistent broker address, for the LoRaWan Server it results: Enabled and with Status with green check.

Which shouldn't be possible.

In the error, crash and debug logs there is nothing about these connectors.
