continuous integration - GitLab Runner unable to restore nuget packages when started from gitlab but can when started locally -

i trying .net project build , test using gitlab ci.

i have downloaded , installed recent version of gitlab runner , registered our gitlab instance. have created following .gitlab-ci.yaml file:

variables:   solution: performance-validation-tool.sln  stages:   - build   - test #  - deploy  build:   stage: build   script:   - echo "restoring nuget packages..."   - 'c:/nuget/nuget.exe restore'   - echo building...   - 'msbuild.exe "%solution%"'   except:   - tags  test:   stage: test   script:   - echo testing...   - 'msbuild.exe "%solution%"'   - dir /s /b *.tests.dll | findstr /r tests\\*\\bin\\ > testcontainers.txt   - 'for /f %%f in (testcontainers.txt) mstest.exe /testcontainer:"%%f"'   except:   - tags 

the important part build action.

if run build gitlab following error of nugget packages:

warning: unable find version '3.5.0' of package 'nunit.console'.    c:\windows\system32\config\systemprofile\appdata\local\nuget\cache: package 'nunit.console.3.5.0' not found on source 'c:\windows\system32\config\systemprofile\appdata\local\nuget\cache'.    https://api.nuget.org/v3/index.json: unable load service index source https://api.nuget.org/v3/index.json.    error occurred while sending request.    remote name not resolved: 'api.nuget.org' 

however if run following command locally:

c:\gitlabrunner\gitlab-ci-multi-runner-windows-amd64.exe exec shell build 

everything works perfectly...

i have created firewall exceptions both gitlab runner , nugget.exe (i downloaded , installed recent version of nugget.exe)

the gitlab runner service logged on same account used run manual exec command.

i used same nugget.exe both gitlab triggered builds , manual exec command.

we behind corporate proxy, there no http_proxy environment variable set. proxy configured in "internet options". did try define http_proxy setting nugget.exe later removed after reading nugget.exe uses system proxy default.

thanks in advance help!

i happened @ service in services list , noticed although had explicitly specified user service, created "local system" account, lacked proxy settings, assume. service corrected , builds properly.
