Problems with IntelliJ starting up


I recently had to do a hard reset on my machine, whilst IntellIj was working.  After rebooting I am getting the following error message:


Anybody had this and found a way to resolved it ?

Please see .

Also try "netsh winsock reset" in the command line and reboot.

Thanks, the issue seemed to resolved itself after a few reboots and being off the network.. I didn't get a chance to try the netsh winsock reset.

Can't believe this still isn't fixed yet. If you don't feel like rebooting (netsh winsock reset) every time a JetBrains IDE doesn't feel like starting, you can generally fix it by typing "ncpa.cpl" into your start menu search, or the "Run..." dialog box, then right-click each network adapter there one at a time and click "Disable" followed by right-clicking again and clicking "Enable" (obviously don't do this if you're remoting into the machine).


Or here's a nice Powershell one-liner to do it for you to run at an elevated (admin) Powershell prompt:

Get-NetAdapter | Disable-NetAdapter -Confirm:$false -PassThru:$true | Enable-NetAdapter

Why would I necro a nearly year old thread to say this? Because it's now a top result on Google when searching for that magical netsh command that makes JetBrains actually start.

It's Windows issue reserving too much common ports, see this ticket for more details and the proper workaround: .

If you can suggest a better solution for cross platform folder locking and IPC that will work everywhere, not trigger antivirus/firewall and handle huge ranges of blocked ports, patch is welcome, this subsystem is open source:
