Starting Appium server programmatically + Windows Driver + C#

Hello Appium community,

I hope you’re doing well. I’m facing an issue while trying to start the Appium server programmatically in my C# project, and I’m seeking your assistance in resolving it.

Problem Description: I’m attempting to start the Appium server using the AppiumServiceBuilder in C#, but I encounter the following error:

Message=The local appium server has not been started. The given Node.js executable: C:\Program Files\nodejs\node.exe Arguments: “C:\Users\mihail.amurov\AppData\Roaming\npm\node_modules\appium\build\lib\main.js” --port “4723” --address “”.
Time 120000 ms for the service starting has been expired!

Environment Details:

  • Operating System: Windows
  • Node.js Version: v18.17.1
  • NPM Version: 9.6.7
  • Appium Version: 2.1.3

Troubleshooting Steps Taken:

  • Checked Node.js and NPM versions, which meet the Appium requirements.
  • Ensured that the specified paths to Node.js and the Appium main script are correct.
  • Verified that there are no port conflicts on port 4723.

Additional Information:

  • I’m running my code from [Your Development Environment].
  • The Appium server starts successfully when launched manually:
  1. Manual Appium Command:
  • I attempted to start the Appium server manually using the Appium command ( appium ).
    returns { "value": { "ready": true, "message": "The server is ready to accept new connections", "build": { "version": "2.1.3" } } }}

And I encountered issues connecting to it after using my code (example at the bottom of this topic).

OpenQA.Selenium.WebDriverException HResult=0x80131500 Message=An unknown server-side error occurred while processing the command. Original error: WinAppDriver server is not listening within 10000ms timeout.

POST requests to the server fail with status code 500.

Session in the Appium Inspector cannot be started:

  1. Manual WAD (.exe) Execution:
  • I tried to start the Appium server by manually executing the WAD ( WinAppDriver.exe ), but I faced similar connectivity issues.
  1. Successful Manual Start Command:
  • Interestingly, the Appium server starts successfully using the following command:
    WinAppDriver.exe 4723
    My code is successfully connected and executed, but the GET returns { "status": 13, "value": { "error": "unknown error", "message": "An unknown error occurred in the remote end while processing the command." } }

I kindly request your help in diagnosing and resolving this issue. If you have encountered a similar problem or have insights into possible solutions, your guidance would be greatly appreciated.

Thank you for your time and assistance.

Best regards, Mihail.

Why is /wd/hub/ path called when the the appium documentation stands on the following:
With Appium 1.x, the server would accept commands by default on http://localhost:4723/wd/hub. The /wd/hub base path was a legacy convention from the days of migrating from Selenium 1 to Selenium 2, and is no longer relevant. As such the default base path for the server is now /.

Was this issue resolved?

@Mihail_Amurov were you able to find a solution? Thanks

Looks like you are using an older client or a client that has not updated to the “/” default path. For now, try starting appium server like this:

appium server -pa /wd/hub

And see if that doesn’t help. More info:

Thanks for replying

No idea. I don’t use Windows or C#. You should post that as a new topic.

Is there a solution for this ticket?
