Samba share not accessible anymore

I have a samba share mounted on an Ubuntu 20.04 server, here is my smb.conf file:

[global]

## Browsing/Identification ###

   workgroup = ****
   security = ads
   realm = ****.GRP

   preferred master = no
   local master = no
   domain master = no
   disable netbios = yes

   server string = %h

   idmap config * : backend = tdb
   idmap config * : range = 5000-9999
   idmap config **** : backend = rid
   idmap config **** : range = 10000-99999

   winbind separator = +
   winbind enum users = yes
   winbind enum groups = yes
   winbind use default domain = yes
   winbind refresh tickets = yes

   username map = /etc/samba/user.map
   restrict anonymous = 2
#   server min protocol = SMB2_10
  server min protocol = SMB3_11

   bind interfaces only = yes

   log file = /var/log/samba/log.%m
   max log size = 1000
   log level = 1

####### Authentication #######

   server role = member server
   passdb backend = tdbsam
   obey pam restrictions = yes

   server signing = mandatory

   allow insecure wide links = yes

   template shell   = /bin/bash

follow symlinks = yes
wide links = yes
unix extensions = no

The share was accessible from any windows domain client using \\share, but now access is impossible, and I'm getting different errors like network name is not available, or username and password are incorrect, or we can't sign you in with this credential because your domain is not available. I can provide more logs, I just don't know where to look for them to include them in this question.
