When you try to access a website on your browser, you receive a message “Err_Connection_Reset,” which means the connection cannot be made. Also, it means the connection has been reset. It’s all because of the connection problem. In other words, the error is due to when the site you are trying to visit is not able to make a connection with the destination site. And the message displayed on the browser does not tell whether the problem is due to server or client or network.
Technically, the browser receives only a finish packet instead of the regular reply package. This is used by Transmission Control Protocol (TCP) to declare the connection’s end.
Reasons for Err_Connection_Reset Error
Common reasons for error “Err_Connection_Reset“:
1. Fault in Network Adapter
Faulty Network Adapter is one of the reasons for the error “Err_Connection_Reset.” It interrupts the network connection and also corrupt the TCP/IP Packet. When the browser tries to make a connection, it will throw the error Err_Connection_Reset.
2. Network Driver is Corrupted
Faulty Network Driver while reassembling the TCP/ IP packet corrupts the package. Then, when checksum routines receive a corrupt packet, it then requests a new packet from the server, and then the packet arrives again, and faulty network driver assembles it again incorrectly. The same process continues, and the server keeps sending TCP/IP packet.
At last, when the process reaches its limit, then checksum routines stop sending a request to the server. Hence, the error message Err_Connection_Reset is displayed in the browser.
