Always get Bad Request - Request Too Long

I hosted the all applications(Dev branch) in server, where Identity server is working as expected but when IS4 admin makes the request for authentication it is authenticated and after “Consent” step the error comes as “Bad Request - Request Too Long”. HTTP Error 400. The size of the request headers is too long. . FYI I could see in browser status bar that requests are circular for admin app and server. Its showing “waiting for [server1 IDS4]…” and then “waiting for [server2 admin]…” and keep showing back and forth. Then error comes as Bad Request - Request Too Long. Any help please… https://test.com/ " Credentials are same as documentation, but try it with email" The applications work well in my local dev machine.

For the ssl configuration, I am using free cloudflare ssl for is4server: Used these settings as it is below:

“CertificateConfiguration”: {

"UseTemporarySigningKeyForDevelopment": true,

"CertificateStoreLocation": "LocalMachine",
"CertificateValidOnly": true,
 .......

} Should I change it to something else? Might be causing this issue.

Here is the log created in is4.admin:

You can verify this issue on test environment with this code snippet - try it in Startup.cs in section - Configure:

app.Use(async (context, next) =>
            {
#if RELEASE
                context.Request.Scheme = "https";
#endif
                await next.Invoke();
            });
