Usage behind proxy server fails about chrlauncher

[IntensivePorpoises]

Also behind a proxy that we use a pac script for, get error "Updates not found for (build) configuration." when I launch chrlauncher. Can manually reach a URL https://github.com/henrypp/chromium/releases/download/(version)/(build).zip
and download it though.

fixed (i hope!).

It doesn't work for me.

When I start chrlauncher for the first time I see the "No updates found for "Chromium 64-bit (stable-codecs-sync)"" message and then "Unable to start browser. (null)" error message which closes the app afterwards.

In wireshark I see multiple requests performed:

At first it works fine: proxy is taken into account and authentication (user/pasword) is transmitted correctly.

A request to https://chromium.woolyss.com/api/v3/?os=windows&bit=64&type=stable-codecs-sync&out=string is done and it returns the correct value.

But then, a CONNECT request is performed to github.
Request to /wpad.dat and subdomains of digicert.com (such as GET http://crl4.digicert.com/DigiCertHighAssuranceEVRootCA.crl) are performed repeatedly.

wpad requests works fine, but all digicert.com requests fails with "407 Proxy Authentication Required" because credentials are not passed. It's strange because the first request pass credentials correctly.
