[BUG] Custom proxy with error "Expecting a valid host string in proxy settings, but found"

[hintdesk]

Description/Screenshot
In my company we have set a corporate proxy. To connect to Internet the application has to use this proxy.
The proxy has the format of "proxy.companyname.i:port".
I have set that proxy over env variable http_proxy und https_proxy. Currently I receive this error

`

Steps to Reproduce

• SDK Version [e.g. 22]: 3.0.0
• How you initialized the SDK:

if (process.env.APPLICATIONINSIGHTS_CONNECTION_STRING) {
console.log('Configuring Azure AppInsights');
appInsights
.setup(process.env.APPLICATIONINSIGHTS_CONNECTION_STRING)
.setAutoDependencyCorrelation(false)
.setAutoCollectRequests(true)
.setAutoCollectPerformance(false, false)
.setAutoCollectExceptions(true)
.setAutoCollectDependencies(false)
.setAutoCollectConsole(false)
.start();
}

Expected behavior
What should I have to do to tell ApplicationInsights SDK that "proxy.companayname.i:port" is a valid host?
