this server is not in your authentication search policy

I have mac machine with os big Sur version 11.1 and i have an issue about active directory 'This server is not in your Authentication Search policy' when i am going to bind with windows server 2019 its bind properly and I can log in with the network user on the mac machine .. but when i just restart the mac then I cant able to login with network user.. f you now go back to the Users and Groups join option it has Multiple entries and shows 2 AD servers,

against one it says 'This server is not in your Authentication Search policy'. One domain is now in capitals (which you can't use) the other is the original but has the error against it. If you check the Authentications Search Policy, then it is in there. If you remove it, you are then unable to see it in order to add it again.

Now if you restart, or log out, you are unable to login in as a domain user.
