I encountered the same issue when running in Travis CI with docker service. At first I upgraded to 4.5.0 and everything was working okay then since about Friday I started seeing the Unable to find a free port exception. I then tried both 4.3.0 and 4.5.2 but saw the same issue.

I was able to work around this issue by adding the environment variable SE_DOCKER as true to my CI and running with version 4.5.2 which is expecting that env var in this commit. After that everything started working as before.
