Proxy Supermarket

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.

In Telegram on PC, proxies can be set up through the application settings. You need to open the "Advanced settings" item, then - select "Connection type". By default, the Windows system proxy is used, but you can specify it manually or disable it altogether.

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.

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.

Open the "Browser Properties" in the control panel, in the "Connections" section of the opened window select "Network Settings". Remove the check mark from the "Use proxy" item, click "OK".
