scalac: Cannot connect to compile server at localhost/127.0.0.1:3200

This error means that the IDE is unable to connect to the compile server java process which it launched on the mentioned port on localhost loopback interface. This usually happens what the process was unable to start, was terminated or the port is used by another process or some other process (antivirus/firewall) blocks the IDE connections/processes your machine.

Please try with antivirus/firewall disabled or make sure that IDE configuration/caches directories IDE executable, IDE installation home are excluded from the scan.

Ok thanks, I see. I'll have a look at that.

Also tried to install latest version of IntelliJ and still have the issue.

Another element is that when I try to run the scala compiler using this icon, it simply can't run and looking at the IntelliJ logs, no error is displayed.

What happens after you click Run? You can share entire idea.log after IDE restart and reproducing, I'll take a look.

Pretty much nothing happens actually.

Please find attached the idea.log below.

Thanks a lot for your help.

Thanks. It looks like the IDE just simply cannot make a connection to the tcp port specified. As mentioned please check AV/firewall programs blocking the IDE connections. Also try if it helps to enable Settings (Preferences on macOS) | Build, Execution, Deployment | Compiler | Scala Compiler | Scala Compile Server | Start process in project directory option.
