Issue
Since upgrading my docker CMS to 4.4.4 from 4.1.1, I’ve been getting error when uploading media files. I attempted rolling back to 4.4.3 but the error persists.
I found the issue. Recently I had to enable HTTPS on the site using NGINX. NGINX was blocking uploads over a very small size, around 2mb. I added the line ‘client_max_body_size 2g;’ to the default site in /etc/nginx/sites-available in the server block and it resolved the issue.
Example:
server{
listen 443 ssl http2;
server_name example.com;
client_max_body_size 2g;
}
