[Bug]: occ files_external:notify gives Icewind\SMB\Exception\ConnectionRefusedException on 33

[oblivioncth]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

For multiple major versions I've ran

occ files_external:notify 1

as a separate process in my nextcloud docker stack in order to enable SMB notifications for the External Files app, and it's seemingly worked without issue. Now, after upgrading to 33, trying to run the above command results in

In Connection.php line 56:

[Icewind\SMB\Exception\ConnectionRefusedException]

The same happens even if I try to explicitly provide the username/password to the command (and that was never needed before anyway). The server itself is still able to connect to the share and I'm able to read/write files with my user account, so it seems only that this command (or the occ tool at large) is affected.

I even cloned out a snapshot of my install when it was still on version 32 to confirm the command executes fine there and it was only after upgrading to 33.

Steps to reproduce

Try to run:

occ files_external:notify 1

as a separate process.
