Blank screenshots when using --headless and --proxy-server at the same time.

If I use chrome without the --headless option, everything works, which means traffic goes through the selected proxy, and when I capture the screens, the resulting images look the way I expect them to.

If I add --headless to the command line arguments, I start capturing blank screens.

I tried both Canary and Chromium.

Is there anything I can do figure out what’s going on? I added logging to the proxy, and I see only one connection happening, instead of several, which is what I see when “it works”.

Let me know if there’s something I can do. Thanks in advance.

For me, adding the --ignore-certificate-errors did the trick.

options = Options()
options.add_argument('headless')
options.add_argument('ignore-certificate-errors')
options.add_argument('--proxy-server=%s' % proxy_url)

driver = RemoteDriver(hubUrl, options=options)

Done with selenium python I run the tests in Selenium Grid (3) with Windows and Linux nodes.

hope this helps

This is hardly a problem with this project, you should file and issue here.

Moreover, I cannot even start Chrome if I set both --headless and --proxy-server at the same time on Linux:

$ google-chrome --proxy-server=socks5://127.0.0.1:9050 --remote-debugging-port=9222 --headless
[0718/200052.562414:ERROR:headless_shell.cc(551)] Malformed proxy server url
