Today i installed 26.0.2 - now it runs.

May 27 '23 22:05 tonyblue2

This may have been similar to #37473 and a fix made it's way into v26.0.2 by way of #38317.

Glad to hear it's working!

Jun 06 '23 12:06 joshtrichards

After updating to version 26.0.2, I have still the same issue. Any ideas for a solution?

Jun 09 '23 10:06 kborgulski

@kborgulski Then your issue has a different cause. You'll need post on the help forum (https://help.nextcloud.com) to rule out an installation/configuration matter. Or open a different Issue if you believe it to be a bug rather than an installation matter, with the details of your environment/installation, since your situation is not exactly the same as original reporter's.

Jun 09 '23 12:06 joshtrichards

@tonyblue2 Actually this is expected behavior when using "Log-in credentials, save in session"

https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage/auth_mechanisms.html#password-based-mechanisms

You'll need to use a different credential option as described.

This is behaving as designed - with your current configuration - since your SMB credentials are only available to NC while you're logged in.

Thanks for the hint. My description above was wrong. I got it right However, the error no longer occurs for me (as described).

I used "Log-in credentials, save in database " for authentication.
