enrolled printer says "Cartridge cannot be used until your printer is enrolled in HP Instant Ink"

[MCLin123]

My printer is displaying "cartridge cannot be used until printer is enrolled in hp instant ink" even though it is enrolled in hp instant link.  when logging into the hp smart website and viewing the overview information about my printer, it says "Unable to connect to the printer.
Check your connection and try again later".  both the printer and computer are connected to the same wifi.  i've already restarted the printer, router, and computer and had no luck solving the issue.  my printer has the latest update and is using the proper instant ink cartidges.

Welcome to the HP support community.

I am glad to assist you to fix the web service connection error on your printer.

Meanwhile, follow these steps to fix the issue.

Turn On Web Services

• Make sure the printer is connected to a wired (Ethernet) or wireless network with an active internet connection.
• NOTE: If you connect your printer to a computer with a USB cable, web-connected printing services do not work.
• If your printer is connected with a wired (Ethernet) connection, check the cable and the lights on the printer’s Ethernet port. The green link light should be steady, and the orange activity light should blink when the cable is connected.
• If your printer is connected with a wireless connection, make sure the wireless feature is on and the printer is connected to the same network as your computer.
• Some printers have a wireless icon and a blue light on the front of the printer. If the printer has a blue light, and the light is on and not blinking, your printer is connected.
• On your control panel, press the HP ePrint icon.
• If your control panel does not have an HP ePrint icon, navigate to Web Services Setup, Network Setup, or Wireless Settings to open the Web Services menu.
• If a summary screen displays, Web Services is already on.
• 
• If a prompt to turn on Web Services or set up HP ePrint displays, follow the prompts to turn it on or set it up.
• 
• If you are prompted to update the firmware, press OK.
