Encountering the 'ERR_CONNECTION_RESET' error in your browser indicates that the connection to the website has been interrupted or reset. This issue may result from various factors, and resolving it involves troubleshooting both your local system and potential issues on the website's server. Here are steps to address the problem:
Check Your Internet Connection: Try accessing other websites to confirm whether the issue is specific to the website you are trying to reach.
Clear Browser Cache: Cached data may be causing conflicts. This action can be performed in the browser settings, typically under the "Privacy" or "History" section.
Disable Extensions: Browser extensions may interfere with website connections. Temporarily disable all extensions and try accessing the website again. If successful, re-enable extensions one by one to identify the problematic one.
Reset TCP/IP: Open Command Prompt as an administrator and type the command 'netsh int ip reset' followed by 'netsh winsock reset.' Restart your computer to reset the TCP/IP stack.
Flush DNS Cache: In the Command Prompt, type 'ipconfig /flushdns' to clear the DNS resolver cache. This can help resolve domain name resolution issues.
Try Another Browser: If the error persists, try accessing the website using a different browser. If successful, the problem may be specific to the original browser.
Disable Firewall and Antivirus Temporarily: Temporarily disable them and check if the website can be accessed. If successful, adjust the settings to allow the connection.
Contact Website Administrator: If the issue persists, it might be on the website's server side. Contact the website administrator or support team to inquire about server status and potential issues.
Check Proxy Settings: Your browser is not configured to use a proxy server that might be causing connection conflicts. Disable proxy settings and try accessing the website.
Update Browser: Outdated browsers may have compatibility issues that can result in connection errors.

By systematically going through these troubleshooting steps, you can address the 'ERR_CONNECTION_RESET' error and improve your chances of successfully accessing the desired website.
