Proxy Pac and Sierra

Hi All,

I have upgraded MacBook Air to macOS Sierra Version 10.12.,

Browsing is not working via "Automatic Proxy Configuration " in Chrome Browser V58.0.3029.81 (64 bit)

I am using .PAC file for browsing in an domain Network . PAC file is getting downloaded through the browser., but while browsing am getting the error, site can't be reached with the below error. "err_connection_timed_out" "ERR_CONNECTION_CLOSED"

Troubleshooting methods that I've tried

My Proxy Server is reachable from the Macbook

My Pac file server is reachable from the Macbook

No Issues in Safari... Its working Absolutely Fine.

Does the URL for your proxy PAC script begin with `http://` or `file://`?

I have this same problem but I'm using a local proxy.pac file with a URL of the form file:///Users/.../proxy.pac.

Firefox works fine with this setting, but Safari fails to connect to any web site that requires a proxy.

I ran a local web server and switched the configuration to use an http: URL instead of a file: URL and then Safari worked, so it's not related to the content of the file but rather to the form of the URL being used. I can't figure out how to make a file: URL work, even though it worked fine before Sierra.

Hi,

I've upgrade to sierra 10.12.1, and I've a very annoying problem with safari. It doesn't open a lot of sites while chrome does. I've configured the company proxy.pac in Automatic Proxy Configuration and up to sierra upgrade it was working better. Now only the intranet sites are opened no chance for google, yahoo end many others. I've to use Chrome or Explorer in Parallel.

Any ideas?

Gianni

Hi Mike,

I had already upgraded to Safari 10.0.1, but problem is always there. Is a "generic proxy problem" of Safari or Sierra? I've to wait until next release?

OK, now it seems to be working fine.

Thanks
