Slow HTTPS requests to all websites in Chrome
We have some weird behavior on a lot of machines here – computers running Windows 10 x64 and Windows 8.1 x64. Using Internet Explorer we face no problems when visiting different websites, but Chrome is very, very slow when trying to access HTTPS websites, and its all HTTPS websites, but only in Chrome. We tested on fresh Chrome installs, even without any users logged into it or extensions installed.
The only thing in Internet explorer which is slow? The download of Chrome. On one machine I even tried to download Chrome through Ninite, but that was also slow!
I have tried scanning the affected computers with Malwarebytes and Windows Defender, but nothing shows up. In every other way the computers work fine, so I don't expect there to be any viruses or the like. I've tried changing DNS settings, reinstalling network drivers, etc., but nothing helps.
Do you have any suggestions?
EDIT: I would've loved to test out any of the suggestions here, but I'm no longer able to test this out, as i no longer work at the place where the issue were.
We encountered this recently and it was a Chrome proxy setting. In the Chrome URL field enter chrome://net-internals/#proxy to see the current running proxy settings.
Test Chrome using different proxy setting flags:
-
Exit any running-instance of Chrome.
-
Right click on your "Chrome" shortcut.
-
Choose properties.
-
At the end of your "Target:" line individually test with these flags:
--no-proxy-server--proxy-auto-detect--winhttp-proxy-resolver -
Launch Chrome like normal with the shortcut.
You can also open powershell and run netsh winhttp reset proxy to remove any proxy server settings in Windows. After doing this navigate back to the Chrome proxy URL from earlier and click re-apply settings.
