UCMDB Discovery Key exchange failed: Host Connection by Shell
Environment: UD 10.21
Discovery Error: "ErrorKey exchange failed: I/O error - read failed: An existing connection was forcibly closed by the remote host (uc)"
When trying to discover a Redhat 7.2 box (hosts sitescope server) the above error is received by "host connection by shell job". No other related CI is discovered for the respective IP address CI. Could this be due to any kex algorithms?
Could you please advise on the above.

How many of your servers have such issue? If only one, you’d better check your permission configuration on that server. May be you can try with different account.
If the issue still exist after you confirm all permission configurations are correct, better prepare commutation logs and probe logs then open a support ticket.
