Samba Winbindd Failing Everyday

Everyday morning on my domain controller running samba 4.7.6-ubuntu winbind fails, If I try to run the command wbinfo -u (to list all users) I get the error

could not obtain winbind interface details: WBC_ERR_WINBIND_NOT_AVAILABLE
could not obtain winbind domain name!
Error looking up domain users

As per a question in the comments

sudo systemctl status winbind.service
