If using Ubuntu/WSL2, you can kill ports if needed like this ($PORT is the port number if known):

$> lsof -ti :$PORT

then...

$> kill $(lsof -ti :$PORT)

or if parse SIGKILL in some cases (big hammer solution):

$> kill -9 $(lsof -ti :$PORT)

Issues: Currently not working on either Ubuntu remote server nor WSL2. Cause unknown. Server starts okay but doesn't connect via browser. Might be JAVA 21 version issue?
