Description
Describe the problem
When a linux system is using a default localhost resolving to ::1 (IPv6 localhost address), IDE won't start because the backend process is only listening to 127.0.0.1:<port>.
Listening on both 127.0.0.1 and ::1 by just providing the port would solve the problem.
To reproduce
To reproduce, just ensure having the following configuration in your /etc/hosts file :
::1 localhost.localdomain localhost
instead of
127.0.0.1 localhost.localdomain localhost
Expected behavior
IDE could support dual stack if in order to be started in any situation. Otherwise it shouldn't rely on dynamic resolution that can end up in an incompatible configuration.
