We are having an issue with files uploading to one of our sites, when proxy is enabled.
When we are trying to upload media files (MOV, MP4) via wordpress when CF proxy is enabled, the upload is very slow, and when the uploading is done, we get “media error”, and the file seems to be broken.
When we are turning off CF proxy and trying to upload, it’s a little bit faster, and the media file works.
There are no errors on server side, and the file’s size is less than 100MB.
Any ideas why the CF proxy might causing this issue?
