Hi All,

We are using an explicit .pac file.  I’ve attached an email which should hopefully provide more context.

Thanks,
Bill

I think this is due to your configuration.

Are you using a WPAD that specifies a direct connection for local servers?  Use system settings won't work then unless it is set up properly.

Take a look at the settings in your http://wpad.example.com/wpad.dat (substitute your network) and replicate in the system configuration.

Look for something like this:
// test for direct addresses
if (isPlainHostName(host) ||
dnsDomainIs(host, ".somedomain.something") ||
(host=="127.0.0.1") )
return "DIRECT";

Hello all,

I’m running into a network setting error and I was wondering if anyone has witnessed the same.

I used to use autoconfig for 60.9 ESR. Starting with 68 ESR I’ve used policies.json. In the Network settings I use “Automatic proxy configuration URL”. However, there is another team that needs to change it to “Use system proxy settings”, and when they do this they can’t connect to audio/video servers. Previously in 60.9 ESR and autoconfig, it worked but not in 68.8 ESR.

Does anyone know or have witnessed this issue? Is it possibly because I set the policy to use a specific proxy which is somehow affecting when other users change it to “use system” instead of “automatic proxy”?

Thanks!


Victor Hoang
