The error is:

 https://127.0.0.1:3001/ failed, reason: connect ECONNREFUSED 127.0.0.1:3001

which should not happen and the test should fail. We have to understand why server is not responding in ubuntu

We have to investigate if this is a non-issue or if it is still happening on ubuntu.
