@Shivangi Thakur,
In your application, you can change the Timeout by following this link that you gave yourself, which can be a .NET component or the platform's native way, increasing the time in "Server Request Timeout", as shown below:

Now, if the weather is good and the timeout problem is on the SSO side and this resource is shared with other systems, better evaluate if it is giving problems on these other systems as well.
