chrome option --proxy-bypass-list=<-loopback> is not working

I setup a mock server on my local port 8500 for testing and behave like a proxy. I have read that chrome will ignore proxy settings for those request from localhost and need to add --proxy-bypass-list=<-loopback> to disable/bypass the rule. It was working until today.

My Configs: System: MacOs Catalina, 10.15.3 Browser: Chrome Version 80.0.3987.149

the args to start chrome is --ignore-certificate-errors,--proxy-bypass-list="<-loopback>",--proxy-server=http://localhost:8500

I use selenium to do the automation and the base url is http://localhost:8080

After running, I can see the "external" urls calls like cdn js files, font files are actually going through the proxy server on port 8500. But I cannot find any localhost calls Then I change the baseUrl to one of my testing environment which is not localhost, for example 10.10.10.10:8080 and I can see all traffic is going through proxy, including traffic to 10.10.10.10:8080

I doubt the new chrome version breaks the bypassing rule since I had an update earlier today.

Please Help! Thank you!

These lines worked for me :

ChromeOptions options = new ChromeOptions();
options.addArguments("--proxy-bypass-list=<-loopback>");
WebDriver webDriver = new ChromeDriver(options);
