directory index of "/usr/html/" is forbidden

[qy2009]

what is the correct user ID and group ID I should use?

I tried this one:
The following user and group id are used, the files should be set to this: User ID: Group ID:

chown -R 100:101 /data/{domain}/html

E.G

chown -R 100:101 /data/yobasystems/html

it returned directory index of "/usr/html/" is forbidden.

then I tried set to my user ID which created the folder. failed as well.

Thats just the default nginx userid, you should really need to both just make sure the directory is writable
