Any suggestions what is wrong?

Okay, I found out what this comes from. It is because, I'm sitting behind a proxy, and one has to expicitly exclue localhost from the proxy in emacs. Not he problem is different though. It now hangs with: Contacting host: localhost:9988

I have turned of the windows firewall just to be shure...

This is how my proxy config looks right now:

(setq url-proxy-services
      '(("no_proxy" . "^\\(localhost\\|10.*\\|*.mpip-mainz.mpg.de\\|127.0.0.1\\)")
         ("http" . "www-proxy.mpip-mainz.mpg.de:8080")
         ("https" . "www-proxy.mpip-mainz.mpg.de:8080")
         ))

What was the issue?

deisi commented 8 years ago

A, sorry didn't make it clear. It is solved by now. The issue is/was, that emacs is very picky when behind a proxy. You have to explicitly remove localhost from the proxy list, as you can now see in my answer above. It is important to add: localhost, as well as 127.0.0.1 to the no_proxy field.
