Nextcloud version (eg, 18.0.2): 18.0.4.2
Operating system and version (eg, Ubuntu 20.04): Fedora 31
Apache or nginx version (eg, Apache 2.4.25): Nginx 1.16.1
PHP version (eg, 7.1): 7.3.10

The issue you are facing:

“Internal Server Error” (From Nexcloud, not from Nginx) when trying to access to a SMB share.

  • This worked perfectly before and stopped to work suddenly.
  • the SMB server is FreeNAS-11.3-U2.1, and the share can be accessed successfully from outside Nextcloud.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Have a SMB share configured in “SERVER_URL/settings/admin/externalstorages”. This screen still show the configuration as valid. (Note: The share Nextcloud name is “SMB”)
  2. Try to access it in “SERVER_URL/remote.php/webdav/SMB”

The output of your Nextcloud log in “/var/log/nextcloud/nextcloud.log”:

I have the exact same issue using the ESXi Image from hanssonit.se

When I add an smb external storage inside the nextcloud GUI, then despite the “green arrow” showing that the connection details are correct, it is not possible to access the share.

Issues range from error screens that the destination cannot be accessed, to being able to access the share but “you don’t have permission to add files” as well as “internal server error”.

The only way how I got it working was to use the smb-share script that comes with the ESXi image from hanssonit.se, which mounts the smb share in the OS, and then inside nextcloud that mountpoint is added as “local” external storage.

So all permissions are fine! But when you add the external storage as SMB inside the GUI of nextcloud it does not work.

My smb share is on an UNRAID nas.

There is an issue on GitHub for this, with some workaround solution in wait of a real fix: https://github.com/nextcloud/server/issues/20622
