This appened after a new installation, before worked fine.
There is a any to know wich is the error, maybe in some error log file somwhere?
Thanks in advance

In the troubleshooting part of the documentation you find some information regarding logfiles as well:
https://docs.nextcloud.com/server/stable/admin_manual/issues/general_troubleshooting.html#nextcloud-logfiles

Keep in mind that for smb, you need some specific PHP-extensions that might not be installed by default on your system.

If you are thinking at libsmbc.php etc… are installed in Nextcloudpi.
About logfile I’m not a informatic so is hard for me to understand, in version 22. worked everything without issue

I found this error s
Any solution?
