Cannot start BrowserMob proxy

I am getting the following error, unsure if the application throwing the errors or Katalon. Any thoughts, please ?

Here are the errors :
2019-04-23 18:03:38.367 ERROR mc.k.k.core.util.BrowserMobProxyManager - Cannot start BrowserMob proxy: java.lang.IllegalStateException - failed to create a child event loop
2019-04-23 18:03:38.367 ERROR mc.k.k.core.keyword.internal.KeywordMain - Unable to send request (Root cause: Address already in use: connect)

try to disable Browsermob in settings

it seems something is running on that address:port combination

@Andrej_Podhajsky. I have not turned it on.

check for disable…

@Andrej_Podhajsky. Thank you. It worked like charm.

happy to help. :slight_smile:
