Error checking the sataus of BM package

Hello All,

After I run the DM package, Package is showing succeeded and
when I click on formula log am getting the below error.

The remote server returned an error: (404) Not Found.  (Attached the screen shot of the same.)

Unable to contact the server

There was no endpoint listening at
http://bwdev.opgpower.com:8000/sap/bpc/files?method=preview&package_size=1000000.

Most importantly,Though the DM package is showing success, no data is generated

Thanks,
