I have nextcloud up and running and I got to the point where I want to add an external storage device that has documents/photos on it to share in nextcloud. I chose SMB/CIFS, the storage is on a Windows 11 machine on the same machine. I am running nextcloud on a Hyper-V Ubuntu instance.

Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 20.0.5): 24.0.3
Operating system and version (eg, Ubuntu 20.04): 20.04.4 LTS
Apache or nginx version (eg, Apache 2.4.25): Server version: Apache/2.4.41 (Ubuntu)

PHP version (eg, 7.4): 8.1.1

The issue you are facing:

Is this the first time you’ve seen this error? Y

Steps to replicate it:

  1. Manually add external storage as SMB/CIFS gives the error in the log file as pasted below.
  2. Smbclient is running ok since connection works fine “smbclient //mymachine/myshare -U myuser”
  3. I am at a loss because I have followed every piece of advice I have seen on other forums including this one.

Not sure which log you mean here....

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.
