How to connect to Sophos Central via proxy that requires authentication

Roman Korchak

Hi

We have just moved to a new Proxy system that requires authentication and our servers stopped communicating with Sophos Central and stopped downloading updates.

I have already checked https://community.sophos.com/kb/en-us/119263 and it will not work for us as we dont have an option to exclude particular sites from the proxy (or rather we cannot open our firewall for particular sites). I have noticed though an option for proxy credentials in config.xml file so I am wandering if we can use that to authenticate an endpoint to our proxy so it can communicate with Sophos Central and download updates.

Thanks
