Problem changing file upload limit beyond 500mb

Vote:
 

Hi!

I need to be able to upload big files in our optimizely-site, and successfully managed to change the limit to 400mb. However, when I increased it again to 600mb it wont accept files of that size, and says "File too big" error. (Im doing the upload in the CMS-editor so its not the users themselves doing them).

Version: 12.15.0

The change I did to make 400mb files work was adding this to startup.cs:

services.Configure<UploadOptions>(x =>
            {
                x.FileSizeLimit = 629145600; // 600MB, (<------- not working, it worked when this was 400mb max
            });
            

            services.Configure<FormOptions>(x =>
            {
                x.ValueLengthLimit = int.MaxValue;
                x.MultipartBodyLengthLimit = int.MaxValue; // In case of multipart
            });

Is there a hard limit to 500mb somewhere? It doesnt seem to be a timeout either, because the upload takes around 50s

Any ideas?

Thanks!

This setting configured the IHttpMaxRequestBodySizeFeature which allow NULL for unlimited. Can you try setting it to NULL? If this has the same issue I'd expect it's likely something set on the server level. Are you on the DXP or self hosting?

I found this forum thread https://world.optimizely.com/forum/developer-forum/cms-12/thread-container/2022/11/file-size-limit-cms-12/ with some things to try as well. Looks like on DXP there was a blocker coming from Cloudflare in this case, might be worth opening a ticket with Optimizely if your DXP
