# Troubleshooting

If you cannot open a file:

- Try again after a few minutes in case the server is overloaded.

- Try to open a different URL. If you can open other URLs, check that the URL was typed using the correct case and does not begin with a space.

- If you are using a proxy server, check that it is configured correctly.

- If other TCP/IP applications, such as e-mail and FTP, are not working, there may be a problem with your network connection.

- In the URL, type the IP address of the server rather than its domain name. If this works, your DNS (domain name system) server may be broken.

- If you are using a modem, check that the baud rate is set to the manufacturer's specification.
