SSH Putty "Server's host key did not match the signature supplied"

[g.lafreniere]

Looking for some help with an issue,

I have two ASR 1002 Routers, One I can use PUTTY and SSH into just fine, the other gives me an error message "Server's host key did not match the signature supplied". Can anyone tell me how to resolve this? I have tried the obvious, which is re-generating another key and also generating a 1024 bit RSA key, and also re-loading the router itself. Can't seem to get around this problem, I can console in and everything looks just fine. Any ideas folks? Thanks for any assitance.

Thanks Pete, this worked for me on my 4351's

Just replaced first of two 4321's with potential clock signal component failure running 9.0.3.15.03.

On new 4321, ssh did not work before or after restoring running-copy from old 4321

I googled the error, and found Pete's post and ran the two commands:

   crypto key generate rsa modulus 2048 label test_key

   ip ssh rsa keypair-name test_key

Worked perfectly.  Thank you!
