Unable to execute Katalon scripts in Sauce Labs

Hi, I’m trying to execute the scripts in Sauce Labs

Followed the below steps to run scripts:
1. Login to SauceLabs.
2. Navigate to ‘Account’ page after logged in and note / copy your 'Access Key’
3. Opened ‘Platform Configurator’ page. Selected the settings that i want and it generated the capabilities
4. Then, In Katalon Studio, opened ‘Remote’ settings and passed SauceLabs settings from step #2 and #3.

Tried with below Remote Web Server URL’s : "https://``USERNAME:ACCESS_KEY``@ondemand.saucelabs.com:443/wd/hub" ``"https://``USERNAME:ACCESS_KEY``@ondemand.saucelabs.com:80/wd/hub"

Then the final step will be selecting ‘Remote’ item for execution

Capabilities used :
platform : Windows 8.1
browser : chrome or browserName : chrome
version : 69.0 or browser_version : 69.0 or browserVersion : 69.0

Katalon Version : 5.7.0 → Build 1

Note: My network is behind the proxy and i had configured the proxy in the Katalon Studio Preferences → Proxy.

Getting below error while executing.

Have a look at this post:

If you are behind proxy, I think you can not connect Katalon Studio with Sauce Labs .

Oh!! I have seen this, it’s disappointing that katalon mentioning the features and getting them released without considering all the scenarios of usage. Most of the organisation have proxy for their network and that should be a high priority use case for connecting to say Sauce Labs/Browser Stack/ etc.
@kazurayam : Thanks for your response, Is this feature available in atleast 5.8.x ??
If not, i hope this feature will get a high priority to be implemented and added to this wonderful tool soon.
