This problem is happening with chromedriver (version 2.37, I think): getting the page source, cookies, url, and a web Element all block or cause the web driver to hang. This does not happen in all cases, only cases where this is shown:
Confirm Form Resubmission This webpage requires data that you entered earlier in order to be properly displayed. You can send this data again, but by doing so you will repeat any action this page previously performed. Press the reload button to resubmit the data needed to load the page. ERR_CACHE_MISS
I can verify this happens in windows 10 and windows Server 2012 R2. There is debug message in the debug.log (provided by chromeDriver):
NtOpenThread: {Access Denied} A process has requested access to an object, but has not been granted those access rights.
Note I have only tested this with https://github.com/tebeka/selenium 's selenium client for golang.
This hangs when getting cookies, does anyone know why?
