Error testing Odata Service, different Port

Hi Gurus, I'm facing a problem which I don't know what happens.

  when testing  the odata services from /IWFND/MAINT_SERVICES () I got 404 error only with my odata service:

and I think because of port configuration, its bringing me the default port 8040, When I put the correct port 8001 it works..

thie problema is, it only happens with my odata service, with all other the port 8040 is bringing values, se below other service:

When I run my app it is requesting in port 8040 and bringing a GET error with 404 again...

I don't know what is wrong with my service and how I can change my service port.

Any help will be very appreciated!.

thanks
