Issue
Iguana instance becomes unresponsive and dashboard cannot be reached
Crash dump files may or may not be generated
Iguana service may be running, but the dashboard is unreachable
Possible Solutions
Case 1: Quick Troubleshooting steps
Restart the Iguana Service
Reboot the Iguana Server
Check for any anti-viruses and/or backup processes running on the server
Case 2: Browser related Issue
Try using a different browser:
In the past, we have seen some issues come up while using Internet Explorer
Recommended browsers:
Firefox, Safari, Google Chrome, Microsoft Edge
Try clearing Browser Cache
To rule out it being a browser related issue, try sending a HTTP/HTTPS request to the web page and it should send a response back:
Open Powershell in Command Prompt
Code Block powershell Invoke-WebRequest uri: http://localhost:6543/It should look something like this:
Case 3: Monitor the Iguana Instance

Check for log and socket usage

Case 4: Too Many Open Sockets Issue
Sometimes our clients will get a “too many open sockets (FD_SETSIZE=2048 reached)” log error on very busy servers. This error occurs when you try to open more than 2048 socket connections for an instance of Iguana.
Run the socket diagnostic command to check socket usage:
Code Block http://localhost:<Iguana port number>/socket_diagnostic.htmlAdjust the IGUANA_WEB_SOCKET_IDLE_TIMEOUT_SECONDS system variable to a lower value (default is 120 seconds) – you can set it as low as one second.
