An error occurred in the upload. Occured to non-admin and when using SSL only

I don’t know what the actual problem is. I’ve tried find the way to fix this error on internet, but not found yet.

So, when uploading images, this message appears on the right side of wordpress image uploader: An error occurred in the upload. Please try again later. This error only happens to non-admin user role and when using SSL(https) only.

If I try to upload some images using Administrator user (in HTTPS or HTTP), the error doesn’t happens. And the same thing when I deactivated the SSL on my server.

I’m using VPS Ubuntu 18.04 LTS Server with Let’s Encrypt SSL Activated.

Is there any way to fix this error? Thanks before.
