Can’t upload annotation to a dataset! the last month uploading dataset and its annotation was working well, right now, when I try to upload the annotation using COCO format or any other format, I got this error:

Could not upload annotation for the [task 228819](https://cvat.org/tasks/228819) Open the Browser Console to get details

and when I opened the dev tools in Chrome, I got this 2 messages in the console:

httpStack.js:96 Mixed Content: The page at 'https://cvat.org/tasks/228819/jobs/322540' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://cvat.org/api/jobs/322540/annotations/a2d11c72-b171-43cb-a16f-81380ba2f517'.
