No this happend after the last security update of samba. 

This is due to a samba update.
SECURITY UPDATE: Weak authentication protocol allowed 
CVE-2018-1139-*.patch: Do not allow ntlmv1 over SMB1

You can easily test this, add 'ntlm auth = yes' to smb.conf and
restart. If this cures your problem, then you have two choices, leave
it alone and put up with a possibly insecure server, or fix your
clients to only use NTLMv2 and remove the line from smb.conf.
