Hello Tharun, Does the ssh connection work from a terminal? ---

Getting this error ssh -p 22 user@host Permission denied (publickey,keyboard-interactive). ---

Are you using a key to log in (I guess so)? Could you try to specify the key to use in order to login? Something like: ```auto ssh -i deployment_key.txt -p 22 user@host ``` ---

I would recommend looking at the logs of the ssh server to see why it’s failing. ---

Same issue. SSH connect work from terminal but Jenkins can’t connect - there are 2 containers in docker compose: - jenkins - remote\_host - there are 2 keys: - id\_rsa3 - id\_rsa3.pub - when connect to jenkins container via: - docker exec -it jenkins bash and try: - ssh -i id\_rsa3 a12@remote\_host → it can connect without password - but when I configure same Jenkins SSH with this id\_rsa3: - Can’t connect to server SSH was generate by: ssh-keygen -t rsa -m PEM -f id\_rsa3 LOGS from Jenkins show → Auth fail and Can’t connect to server ---

would still recommend looking at the sshd logs on the target server. They’ll tell you a lot about why a login request was rejected. Its likely you pasted the wrong ssh keys into credentials ---

True. This advide was very helpfull. When I check remote\_host logs I saw: “key type ssh-rsa not in PubkeyAcceptedAlgorithms”. After I create ssh-key in this way: ssh-keygen -t ecdsa -m PEM -f id\_rsa3 - connect started working. Looks like the issue was related to this topic: Ubuntu 22.04 SSH the RSA key isn’t working since upgrading from 20.04.
