Problem configuring s3 primary data storage

Hello everyone, how are you today? I would like to pick your brain about a problem i am facing.
I am trying to setup Nextcloud with Backblaze bucket as primary data storage.
I followed this tutorial but with NC 24 and when i go to install Nextcloud, i enter all the data and it pops me internal server error, contact your administrator. Double checked config files and permisions and everything is exactly like the tutorial.

Do you think it is because of the version of NC and i might need to tweak something on the configuration?

Screenshot of the error i get after following the tutorial.

Thank you!
