Hello @ramses I am very sorry for not answering for so long, we are overbooked
I don’t know exactly what we changed since this post on the PHP side. I know that in the latest version coming by the end of the month we have two configuration (for node and php), but for your version it was not the case.
Maybe you can wait for the next version (I know we use Minio internaly to test), but the Drive will be depreciated and slowly replaced by LinShare ( linshare.org ) in 2022. Of course it will be still possible to upload files into the discussions but no folders and sharing features.
