cant Can't establish ssh connection: "debug1: read_passphrase: can't open /dev/tty: No such file or directory" and "Host key verification failed."

So as the title say imI'm not able to establish an ssh connection to one of my remote serverservers.

I have the address, username and password for both. I have the address, username and password for both.

The most common answer to this topic is to run ssh-keygen -R hostname. The Problemproblem is on my remote Server iserver I have very limitlimited rights and it gives me the error ssh-keygen: command is not found. usallyUsually commands like service oderor su all givesgive me the samersame error command is not found.

Since imI'm able to create a connection over SFTP with Filezilla, can I manually fix this is Problemproblem? Also, if itsit's important, my .ssh directory is empty, so there is no known_host oderor something like this.

Here ist heis the full output of ssh -v user@server

I use my Windows PC which connects to a remote Serverserver over ssh (letslet's call it Server 1) with PuTTy. On server 1 iI have nearly zero rights to run anything besides scp and ssh and basic shell commands. On this server i, I run ana webshop which backups should stall on an other server (lets call it Server 2).

I wish iI could use sftp, but i cantI can't use it and cantcan't install it on server 1. So I have to go with scp. I tried it with curl sftp://xxx.xxx which forto my surprise did work, but still getgets me an new error curl: (51) SSL peer certificcate or SSH remote key was not ok.
