Hello Team, I have created a new WebUI test through the Katalon project. And I am able to record our application. But I am not able to re-run it. On chrome when I launch the server(URL), it shows below proxy server error. # There is no Internet connection There is something wrong with the proxy server, or the address is incorrect. Try: - Contacting the system admin - Checking the proxy address - Running Windows Network Diagnostics ERR\_PROXY\_CONNECTION\_FAILED However in LAN setting Proxy server is already setup. Can you please confirm what proxy address I need to do. Thanks Sumita ---

Hello I have exactly the same problem with Firefox 52.3.0 (32-bit) and Katalon Studio Version: 4.7.2 Build: 2 Proxy is configured in Katalon’s preferences and I’ve successfully activated Kalone license online. When I start Recording (or Playback later on), Firefox is starting with ‘No Proxy’ in Firefox’s Connection Settings. What to do to force Firefox to start with Proxy configured? Thanks. ---

I’m successful in activation Katalon licence on my network under a proxy by refer to “[https://docs.katalon.com/display/KD/Proxy+Preferences](https://docs.katalon.com/display/KD/Proxy+Preferences)”. However, when running a test case on a browser, it shows proxy issue. I can work around by setting proxy manually when the browser is launched. I think problem is “Katalon starts web browser with a default profile with NO\_PROXY setting” by hardcode. [Log] Logging run data ‘proxyInformation’ with value ‘ProxyInformation{proxyOption=NO\_PROXY, proxyServerType=HTTP, password=, proxyServerAddress=, proxyServerPort=0}’ You should support the Create/Edit Profile keywords so that user can create/edit browser’s profile before launching it. ---

You need to configure proxy settings also on this [preferences](https://docs.katalon.com/display/KD/Proxy+Preferences). Please set it to be the same with your current proxy configurations as well. ---
