Hello everyone, I'm on 6.12.10 (I know, it's a bit outdated) and I'm trying to upgrade. Proceeding with the download and subsequent reboot, I find that the server can no longer contact the outside world, as if the network card has failed. This happens with any version I try to install. I am forced to downgrade and revert to my current version. What can I check? Can I paste my diagnostic file for you? Either post-upgrade when the network stops working, or better yet, a previous one to check if there is any setting that then conflicts with the actual upgrade.
