Encountering the “Could not connect to server; are you sure it’s running?” error in Appium can be frustrating, especially when you’re in the middle of setting up your testing environment. This guide will help you troubleshoot and resolve this issue effectively.

Understanding the Problem

This error typically arises when there is a misconfiguration in your Appium setup or when the server is not running as expected. It is crucial to ensure that all necessary components are correctly configured and operational.

Step-by-Step Solutions

1. Allow Unauthorized Certificates

For Appium versions 1.6.*, navigate to the settings and check the “Allow Unauthorized Certificates” option. Ensure that you are under the “Automatic Server” tab. This often resolves connectivity issues by allowing the server to accept all certificates.

2. Verify Appium Server and Inspector Setup

With newer Appium versions, such as Appium server 1.22.0 and Appium Inspector 2021.9.2, it is important to ensure both are set up correctly. Here are the steps:

  • Start the Appium server before launching the Inspector.
  • Manually configure the desired capabilities instead of pasting a JSON representation directly.
  • Ensure that the platformName capability is included, as omitting it can lead to server-side errors.

3. Utilize Automatic Server Options

For Appium server 1.7, use the automatic server option to start a session and ensure that the correct APK file path is provided. This setup can streamline the process and reduce errors.

Additional Configuration Tips

If you’re using Java, ensure that JDK 8 is installed and configured properly with Appium and UIAutomator. Adjust your system’s environment variables to include the JDK path, which can prevent compatibility issues.

Enhancing Your Testing with Repeato

While Appium is a powerful tool, it can sometimes be slow and tests may become unstable. This is where Repeato can be a valuable asset. As a no-code test automation tool for iOS and Android, Repeato offers a more efficient alternative. It leverages computer vision and AI to create and run tests rapidly, providing a seamless experience for developers and testers alike.
