Answer 1

Download the latest ChromeDriver for your operating system here.

• Upgrade ChromeDriver.
• Execute netstat command through CLI to see if you have reached limit of possible open connections or check if there is another application running on the given port.
• Set Driver Path.
• Check your firewall settings, there is a chance that firewall configuration may be causing the issue.

Answer 2

You need to have the.exe driver in the same directory of your project. If you use chrome - download chrome driver. If you use firefox - download firefox driver. etc.
