I'm trying to use MkDocs and when I run:

mkdocs serve

I get the following output:

INFO    -  Building documentation...
INFO    -  Cleaning site directory
[I 180130 17:24:42 server:283] Serving on
[Errno 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted

I can't find the way what other services are using/running on that ip/socket. Any help much appreciated.

  • windows, thanks. I've already figured it out, virtualbox was causing the problem. – George Garchagudashvili Jan 31 '18 at 2:03

    Please post an answer if possible. Otherwise please close the question since it won't get other meaningful answers given you've solved it. – Twisty Impersonator Jan 31 '18 at 2:04

I've found a solution:

  1. Run resmon for resource monitor dialog
  2. On Network tab search for Listening ports section
  3. Look for the one taking 8000 port (in my case it was a virtualbox instance)
  4. Turn it off and it will work.
