Remote Login to Cisco Router Fails
When attempting to use Cisco Configuration Professional to "Discover" and connect to my Cisco 2921 ISR (Second Generation), I receive the error: "Discovery could not be completed because the security certificate was rejected." SSHv2 login also fails, but with no errors.
On reboot, the console indicates the following errors:
SSHv2 RSA Signature Generation Failed: Status 8
SSHv2 Signature creation failed: Status 22
show ip ssh, displays the key info as expected, and show ssh shows SSHv2 running, but with no connected sessions.
Any thoughts on why remote access spontaneously stopped working?
There has been no change to the router configuration since the last time it worked.
The certificate being used is self signed.
Yes. I've already restarted the router (pulling a known good startup-config), which had not impact.
On reboot, the console indicates the following errors:

This time I was onsite and able to get in to the router, but there's a point to having remote access. If it's going to randomly fail... what's the point in having it?
