If your Web browser displays the message "The connection was reset," it means that a computer between yours and the destination server sent a TCP Reset packet before a data transfer was complete. While this issue can be related to a problem with your Internet connection, it's more frequently caused by a configuration issue or corruption of the data stored locally on your computer.
Test your Internet connection and the performance of the remote server by using the "ping" command. Open the Start menu and type "cmd" in the search field. Press "Enter" to display the command prompt. You can ping a website by typing the command "ping (website name)," such as "ping google.com." Begin by pinging a website -- such as Google -- that typically exhibits short response times; then ping the website giving you the "connection reset" error. If the response time is greater than several hundred milliseconds or you don't receive a response, one of the connection points between your computer and the remote server may have a problem. You might be able to resolve this by waiting and trying again later or by changing your router's Maximum Transmit Unit value to 1,500.
If you receive a "connection reset" error while uploading a file to an FTP server, your browser or FTP client may be operating in passive mode. Passive mode causes your computer to open connections with the server, which helps FTP transfers work behind firewalls and proxy servers. However, some servers may be incompatible with this mode. In Internet Explorer, you can disable passive mode from the "Advanced" tab of the "Internet Options" menu.
Uploading to Web Server
If you receive a "connection reset" error when uploading data to a Web server running PHP, you may be exceeding the server's upload size limit. Resolve this issue by opening the file "php.ini" or "php5.ini" on your server and adding the following text:
post_max_size = 48M
file_uploads = On
upload_max_filesize = 192M
Corrupted Local Files
If you receive a connection reset error when attempting to browse a specific website and other browsers don't display the error, the browser cache or other local files may be corrupted. Clear the browser cache, cookies and history in Internet Explorer using the "Delete Browsing History" option. In Firefox, this option is available on the Privacy tab of the Options window. In Chrome, clear local files using the "Under the Hood" section of the Options menu.
