【Maven】 Cannot connect to the Maven process. Try again later. If the problem persists, check the Maven Importing JDK settings and restart IntelliJ IDEA

Please disable antivirus and firewall. The issue happens when the IDE tries to establish connection to localhost but it is blocked on your machine. Make sure the localhost is resolvable and is accessible for the processes to connect to it using tcp. try using different JDK for Maven imported: Settings (Preferences on macOS) | Build, Execution, Deployment | Build Tools | Maven | Importing | JDK for importer.

P.S. please do not create duplicated requests, it makes it hard follow and to dispatch them all. Thank you.
