How are you trying to adress services? Try using the "/msg nickserv" approach instead and I think you'll see that it works now.
If you wish to use the aliases like "/nickserv" and such you'll have to make sure that Unreal has been properly configured. In this case double check your Unreal config options like services-server and that you have included the right aliases file (aliases/anope.conf).
And just in case double check your u-line block as well.
