Device connectivity problems, cannot resolve hostnames

If you're experiencing "cannot resolve hostname" errors on your device, it usually indicates a problem with your network's Domain Name System (DNS), which translates website names into IP addresses needed to access them; meaning your device can't find the correct address for the website you're trying to reach. 

Troubleshooting steps:

Basic Checks:

• Verify internet connection: Ensure your device is properly connected to the network and has a stable internet connection. 
• Check network settings: Double-check your network settings on the device, including the correct Wi-Fi network name and password. 
• Restart devices: Try restarting your device and router to refresh connections. 

DNS-related checks:

• Check DNS server settings:
  • Access your network settings and verify that the correct DNS server addresses are configured on your Digi product.
  • If unsure, contact your internet service provider (ISP) for the correct DNS servers.
• Flush DNS cache:
  • On your device, clear the DNS cache to remove outdated information that might be causing issues.
  • Consult your device's manual for the specific command to flush DNS cache.
• Use a different DNS server:
  • Try using a public DNS server like Google DNS (8.8.8.8, 8.8.4.4) to see if the issue persists. 

Advanced troubleshooting:

• Check for typos:

Double-check that you're typing the website address correctly, including any "www" prefixes. 

• Check local hosts file:
  • Examine your local "hosts" file on your computer, which can sometimes override DNS settings. 
  • Verify that there are no incorrect entries that might be causing conflicts. 
• Check for network firewall issues:
  • Check if your network firewall is blocking access to the website you're trying to reach. 
• Contact your ISP:
  • If the problem persists, contact your ISP to check if there are any DNS issues on their end. 

Diagnostic tools:

• Ping command:
  • Use the "ping" command in your command prompt to test connectivity to a specific website by IP address. 
• Nslookup:
  • Use the "nslookup" command to check if your device can resolve a hostname to an IP address.
