TCP Reverse Proxy

Open the "Start" menu and type "Browser Properties" in the search box. Then, go to the "Connection" tab, click on "Network settings" and disable the use of the proxy server. Reboot Windows and check if your Internet connection works. If the problem persists, open the "Advanced" tab in the "Browser Properties" window and check the box next to "Delete personal settings", click "Reset" and restart your computer.

It depends on which browser you are using. In Opera, Chrome, Edge a proxy is configured at the level of the operating system itself. In Firefox in the settings there is a special item (in the "Privacy" section).

Error 500 usually indicates an internal server error. When you're getting this error while querying /wd/hub/sessions to Docker Selenium, it might be due to several reasons. Here are some steps you can take to troubleshoot and resolve the issue:

Check logs: Inspect the logs of the Selenium server container to get more information about the error. You can do this by running the following command:

docker logs 

Replace with the actual name or ID of your Selenium server container.

Verify configuration: Ensure that your Selenium server configuration is correct. Make sure that the hub and node containers are properly set up and can communicate with each other. Check the port mappings and network settings.

Update versions: Make sure you are using compatible versions of Selenium server, WebDriver, and any other related libraries or tools. Sometimes, compatibility issues can cause unexpected errors.

Resource constraints: Check if your system has enough resources (CPU, memory, and disk space) to run the Selenium server and nodes. If your system is running out of resources, it might cause the server to return an error.

Firewall or network issues: Ensure that there are no firewall rules or network configurations that might be blocking the communication between the hub and node containers.

Restart containers: If none of the above steps help, try restarting the Selenium server and node containers. This can sometimes resolve temporary issues.

If you continue to face the issue, please provide more information about your setup, including the versions of Selenium server, WebDriver, and any other related libraries or tools you are using. This will help in providing more specific guidance to resolve the issue.

To put a proxy on an emulator, you need to configure the proxy settings within the emulator itself. The process may vary depending on the emulator you are using. Here, I will provide instructions for the popular Android emulators:

BlueStacks:
- Open BlueStacks and sign in with your Google account.
- Click on the "three dots" (⠇) in the top right corner of the BlueStacks window.
- Select "Settings" from the dropdown menu.
- In the Settings window, go to the "Networking" section.
- You will find the "Proxy settings" or "Network settings" option. Click on it.
- Enter the proxy server address, port, and select the proxy type (HTTP or HTTPS).
- Click "Save" to apply the changes.

Nox Player:
- Open Nox Player and sign in with your Google account.
- Click on the "gear icon" (⚙️) in the top right corner of the Nox Player window.
- Select "Settings" from the dropdown menu.
- In the Settings window, go to the "Networking" section.
- You will find the "Proxy settings" or "Network settings" option. Click on it.
- Enter the proxy server address, port, and select the proxy type (HTTP or HTTPS).
- Click "Save" to apply the changes.

Please note that the steps and options may vary depending on the specific version of the emulator you are using.

In PlayStation 4 and 5, setting up a proxy server follows a similar algorithm. It is necessary to go to the "Library", select "Settings", open the tab "Network Settings". In the window that appears, click on "Network". Then choose the type of connection you are using. It will be offered to set the DHCP, DNS and then the proxy server parameters step by step. And here you can enable it by manually entering the necessary settings.
