Unable to connect to Katalon server
Remedy​
Allow the following .exe files to communicate through Windows Firewall. To learn more about allowing apps through Windows Firewall, you can refer to the Microsoft document here: Risks of allowing apps through Windows Defender Firewall.
- geckodriver.exe
- chromedriver.exe
- iedriverserver.exe
These executable files can be located in:Â <Katalon Studio folder>\\configuration\\resources\\drivers.
You may also need to add Google Chrome (chrome.exe) and Firefox (firefox.exe) in the worst case if your current Windows Firewall blocks them as well.
