Windows Server 2019 SMB1 D25 connection problem


I’ve upgraded camera D25M FW to version and now i have problem to store records to external file server. On this server is SMB1/CIFS feature enabled. Firewall is disabled just in case.
In camera I’ve added CIFS_MOUNT_OPTION=domain=serverIP
but nothing helps. I am able to store records only via NFS share. On Server I see that camera is connecting via SMB1

Is there anything I can do with it?
Thanks for any suggestions.
