[BUG] OPC-UA Connector refuses Connection after restart

[SamuelHelbling]

Describe the bug
After restarting the gateway, the OPC-UA Connector refuses the connection.
If I disable and enable the connector manually in the Connectors View, the connection to the OPC-UA server works.

However, I expect the gateway to attempt to re-establish the connection after a certain amount of time without me having to intervene manually.

Connector name (If bug in the some connector):
OPC-UA Connector

Error traceback (If available):

Versions (please complete the following information):

• OS: Ubuntu 18.04
• Thingsboard IoT Gateway version: 3.4.3.1

If I physically disconnect the connection between the OPC-UA server and the gateway, the connection is refused. But after I have re-established the connection, the gateway can connect to the OPC-UA Server automatically. This is exactly the behaviour I would expect when restarting.

Hi @samy4sam, thanks for your interest in ThingsBoard IoT Gateway!
We were trying to reproduce your problem but in our case, Gateway does reconnect automatically.
Try to use the latest version from the master branch and let us know about the result.
