When you configure a 3rd party service sharing account, like a Dropbox or Evernote, Clarify needs to authorize itself with the service. Clarify must temporarily acts as a web server in order to be notified that 3rd party service is allowing Clarify access. This is only done during when configuring the sharing account. It is not repeated each time you upload content to these services.

If you see the error "10013 on socket" during this process the most likely cause is that you have firewall software that is not allowing Clarify to act as a web server. You will need to configure you firewall to allow Clarify to do so in order to finish the authorization process.
