Chrome 72+ seems to no longer accept --proxy-pac-url












7















I have an shortcut on several Windows PCs that points to Chrome with --proxy-pac-url.



Full Target: field in shortcut properties looks like this:



"C:Program Files (x86)GoogleChromeApplicationchrome.exe" --proxy-pac-url=file://C:/Local/Drive/Path/To/proxy.pac


One PC is always on and didn't restart Chrome in a long time. It still runs Chrome 71. On this PC .pac still works and I can access dynamically proxified resources. On the rest, where Chrome was updated to 72 and restarted it no longer works - Chrome tries to access resource directly and fails. Additionally, I can't debug it, since chrome://net-internals/#proxy shows is empty of any info save for re-apply/clear buttons.



So, what broke, how can I debug this and how to make a specific instance of Chrome run with specific .pac once again? Without always swapping options by hand, of course.

          Chrome removed almost all functionality of net-internals for some reason and it sounds like they removed the pac flag that you were using.



          chromium docs link to this site that still lists the flag as valid.

            Also, as suggested in the bug, you can also disable 'Enable Network Service' in chrome://flags to go back to the old behaviour that supports file:// pac files, though that will also be removed in future. Starting Chrome like /Applications/Google Chrome.app/Contents/MacOS/Google Chrome --disable-features=NetworkService has the same effect.
