    OK, I downgraded samba-client to 4.10.4 from here

    https://software.opensuse.org/package/samba-client

    and locked it ...and it works again. ;-)
    Kind regards

    Total nonsense. The use of SMBv1 (30 year old deprecated protocol) is considered a major security risk with well known vulnerabilities. However, just like with Windows 10 it can still be deliberately enabled in a Linux environment. There are numerous thread on the subject anyway. Always pays to read the release notes....

    Sorry, but I don't have the time to read the release notes of thousands of packages updated by TW over a month or so. I don't see any options to anable for the client (!) smb1 in 4.11. Please correct me if I'm wrong.
    Kind regards

    The release notes mention
    It's still possible to allow SMB1 dialects, e.g. NT1, LANMAN2 and LANMAN1 for client and server, as well as CORE and COREPLUS on the client.
    Note: that most commandline tools e.g. smbclient, smbcacls and others also support the '--option' argument to overwrite smb.conf options, e.g. --option='client min protocol=NT1' might be useful.
    The thread Henk linked to (just one of many) discusses how to add an appropriate entry in smb.conf for clients that must connect to SMB1 (NT1 protocol) servers...
    https://forums.opensuse.org/showthre...83#post2918183

    Another caveat to be aware of...
    LanMan and plaintext authentication deprecated
    ----------------------------------------------

    The "lanman auth" and "encrypt passwords" parameters are deprecated
    with this release as both are only applicable to SMB1 and are quite
    insecure. NTLM, NTLMv2 and Kerberos authentication are unaffected, as
    "encrypt passwords = yes" has been the default since Samba 3.0.0.

    If you have a strong requirement for these authentication protocols,
    please file a bug at https://bugzilla.samba.org and let us know about
    the details.

    The problem is not the server (old Buffalo NAS with smb1 only). The problem is the client.

    Again, the question is:Is there an option to access via dolphin a smb1 share with 4.11 installed? I don't see any way yet...
    Kind regards

    Yes, I got that already. The setting in smb.conf is for samba client configuration.

    Again, the question is:Is there an option to access via dolphin a smb1 share with 4.11 installed? I don't see any way yet...
    Make the configuration first, then try navigating to your share in dolphin eg 'smb://jim@nas01.local/'

    I added to the end of /etc/samba/smb.conf

    Code:
    vers=1.0
    on the client machine.

    Subsequently

    Code:
    sudo service smb restart
    Makes no difference. Same error as in opening post.
    Kind regards

    Non one asked you to do that, so I'm not surprised about the result.

    On all my openSUSE-clients i use a shell script to mount my NAS- shares.

    Basically all the script does is
    Code:
    # mount.cifs SERVER-SHARE CLIENT-MOUNTPOINT -o sec=X,vers=Y,user=...
    Values for X and Y can be found with
    Code:
    # man mount.cifs
    With SAMBA Vers. 4.11.0+git.95.c88b5f2c0c6-1.1 (current openSUSE Tumbleweed) vers can range from 1.0 up to 3.11.

    BTW it might be worth to check the Buffalo website (or the forums) for an update for your NAS-OS (my 10 year old QNAP supports higher versions than 1.0).
