Hi Srujan,

When does this error occur? When you try to log in to Crowd, or in some other cases? Is there an issue you experience with using the product, or is there just this error message in the logs?

If you are using a proxy server in front of your Crowd installation, it might be due to misconfigured 'Trusted proxy servers'. One of the validation factors for applications is the remote IP address. If the trusted proxy servers are misconfigured (or for example there are some that are missing), Crowd would assume the source ip is the ip of the proxy server. If the ip doesn't match the ip of the server that created the application session you might see the error.

Please make sure all relevant proxy IPs or IP ranges are configured properly in Crowd. Please see  Configuring Trusted Proxy Servers for more details.
