For me the issue was that the custom service UUID I inserted had upper cases letter instead of lower cases ones. About the issues of @Puneetkumarpal I think the problem is that if you want to use a custom UUID for a service, that UUID can't be 16bits, it need to be 128bits. See this

Thanks @NidasioAlberto for providing a quick answer.
