ERROR: transport error 202: bind failed: Cannot assign requested address

Hi all
When I am trying to use sbt shell in intelliJ it appears the following error message:
Do I miss any settings?
As you can see below, the port does not appear anywhere.
netstat -planet

What's the full command line? Does it work in the terminal outside of the IDE if you copy/paste it?
I do not start any command but rather just click on `sbt shell` as the following:
When I just clicked on `sbt shell ` it shows the message above. I also have global sbt installed.
Thanks
That was already clear from your description. Please try the same command from the first line in the Terminal and see if it shows the same problem.
Copy/paste the complete line here.
It may help if you change the JDK to a different version and/or reinstall the JDK used to run the SBT shell.
Make sure local firewall is not blocking the java process.
When I use the terminal, then it works:
~/scala/plugger$ sbt
[info] Loading settings for project global-plugins from plugins.sbt ...
[info] Loading global plugins from /home/developer/.sbt/1.0/plugins
[info] Loading project definition from /home/developer/scala/plugger/project

Do you mean that?
No, copy/paste this line here and also in the terminal:
I am using Scala version "2.12.8" and it supports only JDK8

Does localhost resolve on your system? Check /etc/hosts, it must resolve to 127.0.0.1, verify with "ping localhost" command.
Here we go:
developer@sweetsoft:~$ ping localhost

For some reason your system blocks java from binding on localhost:39621. It can be a local firewall issue.
As a workaround you can disable this option:
But what I need is, the debug modus. How can I turn off local firewall on ubuntu.
The firewall is inactive. Here is the proof.
sudo ufw status
[sudo] password for developer:
Status: inactive
When I disable the option "Enable debug..." then it work. Yes are right. But still I need the debug modus.
You need to find out why your OS blocks binding on localhost, I'm afraid it's not IDE specific issue.
How can I manually determine the port by myself? Intellij randomly choose a port.
You can't, it's a random port. Your system blocks any port binding from java.
OK. Thanks so much for your help. I appreciate it a lot.
