XF 1.5 There was a problem uploading your file

[Sim]

I've got a problem uploading video files to XFMG - I'm getting "There was a problem uploading your file" errors for larger files, but no errors appear in the logs.

I have the following PHP settings:

• memory_limit = 256M
• post_max_size = 512M
• upload_max_filesize = 512M
• max_input_time = 3600

and on NGINX:

• client_max_body_size 500M;

It seems to be around the 100MB mark that I start having problems

The weird thing is that my dev server is built from the same installation script (although running on a different VPS provider) and I can get larger uploads to work before it fails - although it is possible that I tweaked something else on my dev server and didn't record it.

So there's obviously some other variable affecting uploads that I haven't considered yet - what have I missed?

I do have video upload quota set to unlimited - so that's not it either (and I would expect a more specific error if it were)

Well that's bizarre - I just did a fresh install of XF1.5 + XFMG to a test domain on the same server and then tried some video uploads - they all worked, even the 235MB video.

Edit: found it ... Cloudflare! My production site uses it, this test site doesn't.

Cloudflare Support

support.cloudflare.com

Depending on the plan your domain is subscribed to, Cloudflare limits data uploads to the following sizes:

• 100MB Free
• 100MB Pro
• 200MB Business

... I'm on the Pro plan, so that's what would be causing the limitation.

Now, to work out how to bypass Cloudflare for uploads!
