Describe the bug
Trying to connect the tegde version 1.3.1 fails:

Sending packets to check connection. This may take up to 2 seconds.

ERROR: Io(Os { code: 111, kind: ConnectionRefused, message: "Connection refused" })
Warning: Bridge has been configured, but Cumulocity connection check failed.


ERROR: Io(Os { code: 111, kind: ConnectionRefused, message: "Connection refused" })

We run a version of the tedge-container-bundle

We test on 4 different systems.
The error occurs only on two systems. On the other two it works.

To Reproduce
The error happen independant of the used bridge: builtin or mosquitto.

Expected behavior

The command tedge connect should complete successfully.
