Trying to configure build agent to work with a proxy server

Question

I'm trying to make my build agent work with an already configured proxy server. The proxy server address is : http://MY_SERVER_DNS:8081

On my build machine inside the agent directory I created a .proxy file which contains the above proxy address and created the relevant environment variables (VSTS_HTTP_PROXY_USERNAME, VSTS_HTTP_PROXY_PASSWORD).

After a restart to the build agent service the indicator in VSTS goes red (instead of green). A partial (most relevant I guess) agent log is attached:

{ Request = Method: GET, RequestUri: 'https://siemplify.visualstudio.com/_apis/connectionData?connectOptions=1&lastChangeId=-1&lastChangeId64=-1', Version: 1.1, Content: <null>, Headers:

Any help would be greatly appreciated!

You could first upgrade your private build agent by right-click the agent pool, and then click Update all agents. The latest version of build agent is 2.129.1.

After updating the agent, try to follow the steps in the following link to run a v2 private agent behind a web proxy: VSTS, TFS 2018 RTM and newer:

Pass --proxyurl, --proxyusername and --proxypassword during agent configuration.

For example:

./config.cmd --proxyurl http://127.0.0.1:8888 --proxyusername "1" --proxypassword "1"

I've tried this method as well. But still I couldn't register the agent. When looking at the logs I get this status code 400: { Response = StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.NoWriteNoSeekStreamContent, Headers: { Connection: close Date: Sun, 11 Mar 2018 08:12:50 GMT Server: Microsoft-HTTPAPI/2.0 Content-Length: 324 Content-Type: text/html; charset=us-ascii } What am I doing wrong ? – NRT Mar 11 '18 at 08:55

Make sure that the proxy file that you created doesn't have spaces around the proxy address which you mention in the proxy file. Make sure you trim it off.
