Hi, my cf-release is v200. And I met an issue when scale out the DEA
number with BOSH. When I ssh to my DEA_NEXT node, the log shows:

{"timestamp":1440419081.440199,"message":"em-http-request.errored","log_level":"error","source":"Staging","data":{"error":"Error
downloading: Response status: unknown, Error: ","data":{"droplet_uri":"
http://staging_upload_user:PASSWORD(a)20.0.0.5:9022/v2/buildpacks/608407a4-6c63-4bf2-a64f-02ed8d0db0ce/download"}},"thread_id":17109100,"fiber_id":26594680,"process_id":30334,"file":"/var/vcap/packages/dea_next/lib/dea/utils/download.rb","lineno":43,"method":"block
in download!"}

Then I tried to download it manually, get the following error:

--2015-08-24 13:20:09-- http://staging_upload_user:*password*@
20.0.0.5:9022/v2/buildpacks/608407a4-6c63-4bf2-a64f-02ed8d0db0ce/download
Connecting to 20.0.0.5:9022... connected.

Username/Password Authentication Failed.

And I have ssh to my cloud controller to check
/var/vcap/jobs/cloud_controller_ng/config/cloud_controller_ng.yml, the
username and password seems to be correct:

# App staging parameters
staging:
timeout_in_seconds: 900
minimum_staging_memory_mb: 1024
minimum_staging_disk_mb: 4096
minimum_staging_file_descriptor_limit: 16384
auth:
user: staging_upload_user
password: "PASSWORD"

Any clue for this issue?

i found all new apps cannot be created now. caused by this issue. Any clue
for it?

Finally, I find out the problem, but may not the one I said above. It
seems a little bug exsited.

In my deployment, it will install some buildpacks by default, but perhaps
caused by some network issues, the buildpack not compete. Which make the
dea_next start check the SHA is not match. It continue try to download the
buildpacks. I have to delete all buildpack in CF, as well as clean the
folder /var/vcap/data/dea_next/tmp/* in each DEA, and restart DEA_NEXT.
