Xiaomi Camara can't acccess EX4100 CIFS

Hi, I have a Xiaomi Camera with NAS option and can see easily a directory on a Windows PC but can see the NAS name but when I enter user and password always give error. It looks like camara is using CIFS, is SMB3 compatible with CIFS???
Thanks,
Javier

You can adjust your My Cloud to SMB 1, 2, 3 to see if it helps.
