Why Does This Error Occur?

Several factors can cause this error:

  1. Faulty Network Adapter: If your network adapter is malfunctioning or its drivers are outdated, it may fail to obtain a valid IP address.
  2. Incorrect Network Settings: If your network settings are incorrectly configured, your computer may struggle to acquire a valid IP configuration.
  3. Router or Modem Issues: Sometimes, the problem lies with the router or modem, which may not be assigning IP addresses correctly.
