I changed the proxy settings with the following code:

sudo networksetup -setwebproxy Wi-Fi IP_ADDRESS PORT on USERNAME PASSWORD

It does indeed changes settings, but throws an error saying:

error -25299 attempting to create account and password for proxy

What could be the reason for this? I think it has something to do with Keychain app, since after changing proxy in Network tab, I also need to press Allow/Always allow when this popup is triggered(right after changing proxy settings). Using sudo command above doesn't manage this popup.

Any idea how to solve this problem?
