Why Wordpress Gutenberg oEmbed return 404 or "oembed_invalid_url"

Question

I have wordpress deployed on subdirectory, like this:

1. example.com
2. example.com/blog

on number 2, when i tried to embed video from youtube (i already check that video could be embed) the oEmbed API give 404 when process it with message "oembed_invalid_url"

on number 1, it's ok when embed video

tried to check debug.log (activated that feature), but no logs written to that file espeacially for that process

I deploy it on VM with PHP-FPM and Nginx

is that because my subdirectory or else ?

update:

some screenshoot
