There seems to be a bug on Chrome 64 that makes certain websites load very slowly.
You can see the following on Sauce's chromedriver logs:
[14.252][INFO]: COMMAND Navigate {
"url": "https://ops.qa.heal.com/dashboard#CV-UHRFW"
}
[14.252][INFO]: Waiting for pending navigations...
[14.969][INFO]: Done waiting for pending navigations. Status: ok
[314.253][SEVERE]: Timed out receiving message from renderer: 299.283

[314.254][SEVERE]: Timed out receiving message from renderer: -0.002
[314.255][INFO]: Done waiting for pending navigations. Status: timeout
[314.255][INFO]: RESPONSE Navigate timeout
(Session info: chrome=64.0.3282.119)
This can be reproduced locally as well, which means this is not Sauce-related.
We believe that this is related to this bug: https://bugs.chromium.org/p/chromedriver/issues/detail?id=2273
The good news is that this seems to be resolved with a combination of Chrome 65 and chromedriver 2.35. At the time of writing, Chrome 65 is still in Beta. Running tests with the following desired capabilities appears to alleviate the problem:
'browserName': "chrome",
'version': "beta",
'chromedriverVersion':'2.35'
