Teleport ECMWF user@jump.ecmwf.int: Permission denied (publickey).

There seems to be something wrong.

  1. install teleport (13.3.26)
  2. copy and paste ssh config from docs 
Host jump.ecmwf.int shell.ecmwf.int
    HostKeyAlgorithms +ssh-rsa*,rsa-sha2-512
    PubkeyAcceptedKeyTypes +ssh-rsa*
    User [ECMWF USERNAME]  
# For ecgate and Cray HPCF
Host ecg* cc*
    HostKeyAlgorithms +ssh-rsa*,rsa-sha2-512
    PubkeyAcceptedKeyTypes +ssh-rsa*
    User [ECMWF USERNAME]
    ProxyJump shell.ecmwf.int
# For Atos HPCF
Host a?-* a??-* hpc-* hpc2020-* ecs-*
    HostKeyAlgorithms +ssh-rsa*,rsa-sha2-512
    PubkeyAcceptedKeyTypes +ssh-rsa*
    User [ECMWF USERNAME]
    ProxyJump jump.ecmwf.int

Note: using only version up to 13 is allowed currently at ECMWF.

just trying to login results in a permission denied:

$ tsh login --proxy=jump.ecmwf.int
# browser opens and I login using my credentials

# keys are present
$ ssh-add -l
