Silkroad "C9 Error - Server Connection Failed" Error and its Exact Solution

Silkroad "C9 Error - Server Connection Failed" Error and its Exact Solution

One of the most common and annoying errors that Silkroad private server players encounter on the sro_client.exe screen while trying to enter the game "C9 Error" (A connection to the server could not be established) warning. This error indicates that the player's computer cannot reach the GatewayServer module on the server, or even though it can reach it, the filter (Guard) interrupts this connection. Through this guide, you will learn how to completely solve the C9 error on the server side.

Method 1: Checking Whether GatewayServer and Ports Are Open

The number one cause of the C9 error is that the **GatewayServer.exe** module that welcomes players on the server is down or crashed:

• Check the server desktop. Make sure the GatewayServer module is running smoothly and is not freezing.
• It is the main door of the Silkroad game that opens to the outside. 15779 You can check whether the (Gateway Port) port is listening on the server or not from the Windows Command Line (CMD).netstat -anoCheck with the command. If the port is closed, players will directly receive a C9 error.

Method 2: IP Blocking (Global IP) Settings of Guard (Filter) Software

If you are using Guard software on your server to prevent cyber attacks, this software may have mistakenly detected the IP addresses of proxy or regular players as attackers and banned them due to instantaneous traffic density:

1. Open the interface or log folder of your Guard program.
2. Banned IPs or Flood/DDoS Protections Check out the tabs.
3. If many players started getting the C9 error at the same time, you may have set the "Connection Limit" setting on Guard too low. Make it easier for real players to enter the game by increasing the maximum request limit per second from a single IP address (e.g. from 5 to 20).

Method 3: IP Input and Media.pk2 (DivDiv) Edits

If the server opens without any problems on your computer, but outside players receive C9, the IP address in the client (pack) is incorrect:

• in the pack file you distribute to the players.Media.pk2Open the file with a PK2 Editor.
• inside DIVISIONINFO.txt orgateway_string.txtExtract the files and examine them.
• Make sure that the IP address written here is the external IP address (Global WAN IP) of your server. If Local IP (192.168.x.x or 127.0.0.1) is left written, outside players cannot access the server and receive C9 error.
