Ok, I start to feel like a complete idiot.
What worked in the past: I am using the version 0.6 of the autorouter. I'm starting it manually using the shell script (I'm on a Mac using Chrome). The autorouter starts without problems.
Now I choose the Autorouter in EasyEDA in the PCB view and the local autorouter is detected an preselected. I simply try to click on "Run" (I have done this quite a few times in the past), the existing connections are deleted (as configured) and then, nothing happens. No reaction, no window popping up, the Autorouter config window does not close, the background process in the shell window doesn't show any activity. Everything is quiet. If I click on the "Run" button again a dialog box pops up stating that I cannot start until the previous autorouting activity has finished.
The same happens if I choose the Cloud as autorouter server.
What am I doing wrong?
Cheers, Joe
