How to debug cider on emacs?

Question

I have an issue using cider: emacs freezes after nREPL server started on 54308 is written. Cg helps, but I have cider not working. My question is: how can I debug cider and get some usefull output to find the source of this problem?

PS After a long time I get error in process filter: error during connect: connection timed out . But I would like to debug underlying process (as nrepl-server is started).

Mx toggle-debug-on-error should make it easy to obtain the stacktrace of the problem. After that you can you use any general debugging technique (personally, I'm fond using the debugger). I see you've also reported your problem here - that's always a good idea.
