Proxy error while checking for updates

[pattarom]

Hi,
I receive an error while checking the updates at program startup.
Error is 403 (proxy authentication required).
I'm behind a proxy that require authentication, there is a way to pass proxy credential to FreeFileSync or alternatively manual set a proxy?

Thank you in advance
Michele

FreeFileSync is using the proxy settings from Internet Explorer.

I understand this, but my proxy require authentication and FFS do not provide any credential, so I receive error 403.
There is a way to manually set a proxy server, so I can set an alternative proxy that not require explicit authentication?
