This section describes how to troubleshoot the following screens that may appear when users access Cybozu products.

When "Web page not found" or "Web page not displayed" is displayed, possible causes are as follows.

• The access URL for the product is not correct.
• The Web server has not been installed.
• The Web server does not have a fixed IP address.

• Any security software or firewall is running.

To use Cybozu products, you need a Web server.
When you have migrated your server but a Web server has not been installed, install a Web server on the destination server.
For details on how to install a Web server, refer to how to install Web servers.

If the installed Web server is not running, you cannot access Cybozu products.
First, check that the Web server is running and start it if it is not.

1. Start the Web browser.
2. Enter "http://(server name or IP address)/" in the address field.
3. Check the displayed screen.
   Confirm that the welcome screen of the Web server, such as IIS and Apache, is displayed.

If you cannot access the Cybozu product from client devices, temporarily disable the server firewall and check whether you can access it.
For details on the firewall in Windows, refer to the help page of Microsoft.
Turn Microsoft Defender Firewall on or off

After you check the access to the Cybozu product by temporarily disabling the firewall, we recommend that you enable the firewall and open the port number used by the Web server communication in your production environment.
The ways how to allow the communication for each port number vary depending on your environment.

The usage of each software varies depending on each product.
For details, refer to the user manuals for each product.
