How to Fix Connection Errors with Graphisoft Services?

In some cases, a problem may occur that prevents connection to Graphisoft services. This can cause the application or certain online features to stop working correctly.

This problem is usually caused by a system-level block, typically related to the hosts file, which controls how the computer connects to certain domains.

2. In the Terminal window, type the following command:

sudo nano /etc/hosts

3. Press Enter.
4. Enter your administrator password when prompted.

Step 2 - Clean up the file entries

Once the file is open, you'll see several lines of text.

• Lines starting with # are comments and don't affect the system.
• Delete any other line that appears in the file.

Note: These entries can block the computer's connection to certain online services, including Graphisoft's.

Step 3 - Save the changes

Windows

1. In Notepad, click File.
2. Select Save.
3. Close the text editor.

After completing these steps, you should be able to access Graphisoft's services normally again.
