Can DNS problems cause Steam error code 50, and what steps are involved in flushing DNS or changing DNS servers?

Yes, issues with DNS (Domain Name System) resolution can prevent Steam from properly finding and loading web pages. To fix this, you can flush your DNS cache by opening Command Prompt as an administrator and typing `ipconfig /flushdns`. Another solution is to change your computer's DNS servers to public ones like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1) in your network adapter settings.
