There were two problems with this as it turns out:
First:
My web.config was not properly set up to handle a dot in the URL.
So I changed it to this:
<system.webserver>
<handlers>
<clear />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="/*">
verb="*" type="System.Web.Handlers.TransferRequestHandler"
preCondition="integratedMode,runtimeVersionv4.0" />
</add></handlers>
</system.webserver>
Also in my URL i use Recruiters, but I added the routeconvention to the Addresses route.
So I also added it to the Recruiter route like this:
config.Routes.MapODataRoute("Recruiters", "Recruiters", recruitersBuilder.GetEdmModel(), new DefaultODataPathHandler(), conventions);
And it works.
