Just replaced first of two 4321's with potential clock signal component failure running 126.96.36.199.03.
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!
