The cause of these "bugs" are security updates and windows removeing/disabling smb1. 
Samba/Windows are disabling SMB1 and changing the defaults for smbclient from smb1 to smb3. 
Take also note of this: 
Every windows 10 1709 and up please note that.. 
If you dont use your windows 10 for 2 weeks, SMB1 is automaticly removed. 
After you reinstall it, it wont be removed anymore. 
Some related bugs:
This is your problem. 
i believe this one is also related to this problem. 
one to watch out. 
Do not allow ntlmv1 over SMB1 when it is disabled via "ntlm auth".
( fixed, but reopened ) 
samba 4.7 is where the default setting changed.
client max protocol Effective SMB3_11 default changed
Based on what i've seen on the samba (bug) list, i dont think this is fully fixed. 
I hope this info helps out a bit.
Best regards,
