When accessing NFA using IP Address or Host Name you may get a 500 error. There will be no additional details. However when you add “/ra” and the end the page loads fine.
If you look at IIS logging you will find a “ASP_0164_:_80004005” error which is an “Invalid_TimeOut_Value” issue.
This error occurs because ASP timeouts cannot exceed 1440 minutes (1 day). The setting change must be made in NFA 9.3.x in the SSO tool.
NFA 9.3.x and later.
