I have a Jenkins installation on Windows Server which consists auf one master node and two build nodes. Jenkins master as well as the build nodes are running as windows service under a domain service user.
For test purpose I created a pipeline where a visual studio project is retrieved from git repo in the domain, after that the project is compiled and tested via msbuild and vs.test.
The test itself includes a webservice call to an IIS where a web service is running.
In Jenkins (Master) I have configured the proxy information (proxy, port, user, password)
On the master node the pipeline works fine no errors. On the build nodes I get an 407 proxy authentication when it comes to the web service call in the tests.
I think I already tried a lot (Windows Proxy Configuration on the build nodes, Java arguments Dhttp.Proxy,...) Nothing solved that issued and now I am puzzled and have no further ideas how to solve this.
I think your proxy server is not open it requires your credential. you need to pass like
user:password@proxyserver:proxyportor you can use some third party service like cntlm
