Home does not exist - external primary storage

Hi,
i want to activate S3 external storage as a primary storage (on nextcloud with existing users, of course o know that user cannot acces their files). I did it in config.php and now users cannot login. I see in log of nextcloud error which say that “Home does not exist”.
Do you have any experience with this?

Thank you very much!


Nextcloud version (eg, 10.0.2): 12.2.0
Operating system and version (eg, Ubuntu 16.04): Debian 8
Apache or nginx version (eg, Apache 2.4.25): Apache 2
PHP version (eg, 5.6): 5.6
Is this the first time you’ve seen this error?: Yes
