Network connections for online license activation and floating license servers

To activate and use an ID-based license, your computer may need to reach two different Materialise servers:

  • The End User Portal (EUP) — used for online activation of any ID-based license, whether that's a local license on your own PC or the floating license running on your License Server. Not required if you activate offline.
  • Your License Server (FLS) — relevant only if you use floating licensing. Once your License Server itself is activated (via EUP or offline), each client PC on your network also needs to reach that License Server directly to check out a license.

This guide walks through the network configuration for both. If you use floating licensing, you'll typically need both parts; if you only use a local license, Part 1 is all you need — and only if you activate online.


Part 1 — Connecting to the End User Portal (EUP)

Use this section whenever you activate an ID-based license online — for a local license, or for your floating License Server. If you activate offline instead, you don't need an EUP connection and can skip this part.

Step 1: Allow the required IP addresses

Ask your IT team to allow outbound connections to the following addresses:

Type Address
IPv4 185.146.152.64/27
IPv6 2a07:4f80:20:200::/56

Step 2: Confirm the port is open

EUP uses the standard HTTPS port, 443. Make sure your PC can reach this port over the network — most corporate firewalls already allow outbound HTTPS, but it's worth confirming with IT if you're behind a restrictive proxy or firewall.

Verify it worked

Try activating your license online. If activation completes, you're done.

Still not activating? Update your trusted root certificates

If your PC can reach EUP but activation still fails, outdated or missing root certificates are the most common cause. To refresh them:

Open PowerShell as Administrator.

Run the following two commands, one at a time:

  1. Certutil -f -generateSSTFromWU root_store.sst
    Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root -FilePath .\root_store.sst
    

Try activating your license again.


Part 2 — Connecting client PCs to your License Server (FLS)

Use this section only if you use floating licensing. This is a separate, internal network step: after your License Server has been activated (Part 1), each client PC on your own network still needs to reach that License Server directly to check out a license.

If a client PC can't connect, this is most often because the Windows Firewall on the License Server is blocking the incoming connection.

Step 1: Ask your IT team to open the port

The License Server uses TCP port 7070. The safest option is to ask your IT team to allow this port through the firewall on the machine hosting the License Server, so the firewall stays enabled everywhere else.

Step 2: No IT team available? Configure it yourself

If you manage the License Server machine yourself, you can open the port directly:

  1. Press Windows key + R, type wf.msc, and press Enter. This opens Windows Defender Firewall with Advanced Security.
  2. In the left panel, select Inbound Rules, then click New Rule in the right panel.
  3. Under Rule Type, choose Port, then click Next.
  4. Under Protocol and Ports, choose TCP, enter 7070 as the specific local port, then click Next.
  5. Under Action, choose Allow the connection, then click Next.
  6. Under Profile, check Private, Domain, and Public, then click Next.
  7. Name the rule FlexNet License Server Port 7070 and click Finish.
  8. (Optional but recommended) Repeat the same steps under Outbound Rules to create a matching outbound rule.

Step 3: Restart the License Server service

  1. Open Task Manager (Ctrl + Shift + Esc) and go to the Services tab.
  2. Find FlexNet_Embedded_Local_License_Server, right-click it, and select Restart.
  3. Confirm its status shows Running.

Step 4: Connect from the client PC

  1. On the client PC, launch your ID-based product and open the Materialise License Wizard.
  2. Click the second button under the key-shaped icon on the left, then select Add New Server.
  3. Enter the IP address of the host PC (the License Server) as the Host Name, and keep the default Port Number, 7070.
  4. If the connection succeeds, the Status will show Active.

Verify it worked

Once the client shows a Status of Active, try checking out a license. If it succeeds, the connection is configured correctly.


Still having trouble?

Double-check with your IT team that no additional network layer (proxy, VPN, SSL inspection) is blocking the connection, then try again. If the issue persists, contact Materialise Support for further help.
