No problem with this link

I think I am reading you have made customisations ?
Have you checked in the debugger where the problem might be ?

Do you have any other non standard pluings installed ?

I don't have problem with those links as well they work fine. The problem is when the links are :

https://www.abc.com/XXXXX/longlinkhere-after32-charactersitsslow-after40neverloads

I add redirect 301 to change those long to small but that did not work because it never enters the middleware, so finally sorted it by using IIS URL Rewrite module and it redirects them to shorter URLS.

Like this one
https://v45demo.selectsystems.com.au/accommodation/longlinkhere-after32-charactersitsslow-after40neverloads-longlinkhere-after32-charactersitsslow-after40neverloads

Dont know what you are doing differently ?

Does the rules below have anything to do with this, but if they did it would act on all URL not just long ones?

    

endpointRouteBuilder.MapControllerRoute(
       name: "CustomCategoryRoute",
       pattern: $"{lang}/carparts/{{categorySlug}}/{{make}}/{{model}}/{{vehicle}}/{{makeID}}-{{modelID}}-{{ktype}}",
       defaults: new { controller = "Catalog", action = "Category"}
   );

endpointRouteBuilder.MapControllerRoute(
    name: "SpecificCategoriesRoute",
    pattern: $"{lang}/carparts/{{categorySlug}}",
    defaults: new { controller = "Catalog", action = "Category" },
    constraints: new { categorySlug = endpointRouteBuilder.ServiceProvider.GetService<CategoryConstraint>() } // Custom constraint for allowed categories
);

endpointRouteBuilder.MapControllerRoute(name: "MakeModelVariant",
     pattern: $"{lang}/carparts/{{term}}/{{make}}/{{model}}/{{vehicle}}",
     defaults: new { controller = "MakeModelVariant", action = "Index", term = "", make = "", model = "", vehicle = "" });

I am using a simpler form maybe it is the constraints option you are using ?

            urlPattern = "accommodation" + "/{SeName}";
            endpointRouteBuilder.MapControllerRoute("Nop.Plugin.Apollo.Front.Accommodation", urlPattern,
                new { controller = "Apollo", action = "AccommodationFront" });

Do you restart the app after make changes to the MapControllerRoute parameters ?

It acts same on local host and live and have restarted app many times. I trimmed down the urls to max 32 characters after /carparts/ and every url works instantly. Strange but that is how it is.
