Timeout not respected

[mneirynck]

Hi,
I'm running this exporter as a container next to our kamailio container on AWS and it looks like the the timeout is not respected.
For example:

Results in the following log entry:

The connection is refused, because the kamailio container was still starting up at that time:

I'm using the following command syntax:

I'm not in any way proficient with Go, so no idea where it might be going wrong.
If I bootup a different container or EC2 instance with the binary the connection works without a timeout if the kamailio is booted completely.
