SSH Connection The authenticity of host can't be established. ECDSA key fingerprint is SHA256:—————————-

Asked by Praveen Kumar Selvam

Dear all,
I cant able to connect from one ip to another ip (same network connected)using ssh , without providing a password.
I have generated a ssh key
ssh-keygen -t rsa
After entering this command in terminal, it gives me private key and public of one system( for example: user1@user1)
After, I am giving a command
ssh-copy-id user2@user@

The authenticity of host ‘xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)’ can’t be established.
ECDSA key fingerprint is SHA256:—————————-
Are you sure you want to continue connecting (yes/no)?

I cant able to connect to user2@user2, I have some problem in my ssh_config files, my permission are getting denised or refused by user2@user2, whereever I try to connect from user1@user1

Kindly, please help me guys. Thank you in advance.

With Regards,
Praveen kumar System
