Problem

This article goes over how to resolve the SOLIDWORKS Material Web Portal error "The SOLIDWORKS Materials Web Portal cannot be accessed". This behavior is due to a specific internet security setting issue that SolidWorks issued the bug SPR 1221067 for and is fixed in SolidWorks 2022 SP01 & newer. It is not a Matereality server-side/website issue.

Follow these steps to replicate the issue:

1. Run SOLIDWORKS versions older than 2022 SP01
2. Load the Simulation Professional or Simulation Premium Addon
3. Open a part, right-click Material in the FeatureManager design tree, and select Edit Material
4. In the Material dialog box, select "Click here to access more materials using the SOLIDWORKS Materials Web Portal" on the lower left side.

Solution 1: Upgrade SOLIDWORKS

If you are using a SOLIDWORKS version older than 2022 SP01, upgrade to SOLIDWORKS 2022 SP1 or newer to resolve the bug.

Solution 2: Change Internet Security Settings

Affected users have reported that the issue no longer occurs after performing the following steps. Contact your IT department before making any security-related changes:

1. Close SOLIDWORKS
2. Type 'Internet Options' or 'inetcpl.cpl' in the Windows Start menu and hit Enter
3. Click on the 'Security' tab, then click on 'Trusted Sites'

4. With the 'Trusted Sites' zone still selected, click on the 'Sites' button
    

   

5. Temporarily uncheck the "Require server verification (https:) for all sites in this zone" option if it is active
6. In the "Add this website to the zone" dialog, add *.solidworks.com exactly as it appears below

7. Click the Add button
8. Re-enable the "Require server verification (https:) for all sites in this zone" option (if desired or if it was previously active)
9. Click Close                                                        
10. With the 'Trusted Sites' zone still selected, click on the 'Custom level' button

11. Scroll to the Miscellaneous section (approximately halfway down in the list)
12. Set 'Access data sources across domains' to 'Prompt' instead of 'Disable'
13. Click 'OK', then click 'Yes' if prompted 'Are you sure you want to change the settings for this zone?'
