How I do that log review?

@ArturoJGarciaJ Thanks for the link, I already did the upgrade, but neither that worked, I still receiving the error "server not responding"

Since this release and the upgrade to HigSierra 10.13.3, my VPN is not working at all! I was, but not anymore. There is any fix? Use to be an FTP site to download firmware revisions, the site is no...
