[Need support]: Is imitator is must to make use of healenium?

[srinivasrpg]

Describe the problem

We have deployed the Healenium backend in a server with 7878 and 5432 ports running and accessible outside the server.
But for some reason, we are unable to allocate an accessible port for the imitator.
When we try to execute the test suite in Jenkins(Parallel mode), we can see the heal isn't happening and we suspect Healenium backend is getting reset after each run.

Is this issue due to the imitator not working? or anything else we are missing?
Healenium-web version 3.2.4
Selenium: 3.141
This is our Healenium-properties file
recovery-tries = 1
score-cap = 0.8
heal-enabled = true
hlm.server.url = http://xxx.xx.xx.xx:7878/
hlm.imitator.url = http://xxx.xx.xx.xx:8090/
serverHost = xxx.xx.xx.xx
serverPort = 7878
imitatePort = 8090
8090 is not working or accessible outside the server
