bsumners

Hi, I am trying to access the article below. I was able to access it a few days ago but now it says "Oops, You're not authorized to access this page." Networking ports and domains used by Ultimaker https://support.ultimaker.com/hc/en-us/articles/360012113719 I need the contents of the article so I can work with my IT to hook up our new printers to our network. How do I go about resolving this? Thanks, Bobby
