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

[g.lafreniere]

Looking for some help with an SSH issue,

I have 2 ASR-1002 routers, one is my primary and the other is a backup router for redundancy and I am using HSRP. On my primary router I can use PUTTY and secure shell into it without any problems, when I try to secure shell into the backup router it gives me an error message "Server's host key did not match the signature supplied". My question is how can I resolve this or is this because I am using HSRP?  I have tried the obvious which is re-generating a new key and also re-generating another key at 1024 bits, and also reloading the router itself. I can't seem to get around this problem. I can console into it and everything looks fine and I don't see anything in it's current configuration that would be causing this. Any ideas folks? Any help would be greatly appreciated.

Hi
HSRP is not the issue here
Can you telnet to the back up router?
Can you post sh run and sh ver from the router ?

Reza,

For security reasons we have telnet turned off. Also, due to security reasons I can't post my sh run. On the sh ver, the primary and secondary are identical, so I can't see anything from there as to what would cause this as I can SSH to the primary but not the secondary. Very intriguing. Any more thoughts? Thanks much.
