I am brand new to ASP.NET development. I’m trying to get my org’s app running in a new environment. Users can log in, but instead of being taken to their landing page, the login page reappears. Through logging I can confirm that the landing page’s Page_Load function terminates correctly, and I’m using the exact same code that works in other environments. Also, there’s no explicit Redirect() in the code path. I’m wondering the there’s an IIS issue. What are some things I could look at in IIS to help me find the issue?

Here’s the Page_Load function if it helps:

protected void Page_Load(object sender, EventArgs e) {
    try {
      ///some code here that throws an exception
    } 
    catch(Exception ex) {
       LogStr("In catch block");
       return;
    }
}

TIA!
