Periodic ERR_TUNNEL_CONNECTION_FAILED in Chrome

[Maros Hluska]

I'm using this with Capybara / Selenium WebDriver and notice sporadic ERR_TUNNEL_CONNECTION_FAILED errors when trying to load a page. Refreshing doesn't help. Some attempts work, some don't. I don't see any other error messages so I'm not really sure how to debug this. The only variable that changes between attempts is the upstream proxy hostname.

Versions:

chromedriver: ChromeDriver 2.36.540469 (1881fd7f8641508feb5166b7cae561d87723cfa8)
chrome: Version 68.0.3440.106 (Official Build) (64-bit)
capybara: 3.6.0
capybara-webkit: 1.15.0
proxy-chain: 0.2.4

Running the ps command, here's how the process looks that Capybara spawns:

I tried removing most of the command-line arguments and executing manually but the issue persists. I'm leaning towards this being an issue with the VPN provider. I'm going to close for now.
