SOLVED. Samba doesn't work on vip machines

Hey. I try to connect to SMB and nothing happens, not even a timeout error. Nmap sees port 445, but smbclient, nullinux and others do not.

I previously used VIP and there were no such problems.

I revoked the ovpn certificate, changed UDP to TCP, used a static IP, did not help.

I will be glad for your help
