Reproduced by running dotdocker start

Expected behavior is that dotdocker will start.

See attached screenshot.

Docker and dotdocker have both been stopped and restarted. dotdocker -V returns 1.4.2. dnscrypt is bound to port 53.

Now it's working after the latest restarting of docker, dotdocker restart, and sudo dotdocker start

Resolve this problem by:

  1. installing a new version (1.4.2) that doesn't bind to port 53;
  2. running dotdocker stop after the new version is installed (because this will remove the old container that was left dangling. note: the older version wouldn't have removed the container with this command, so you must do it /after/ installing the newer version);
  3. run dotdocker start
