ISE 2.3 SFTP repository error

[dwarren011]

After upgrading to 2.3 from 2.2 I am unable to validate the SFTP repo that worked prior.  In another enviornment where I have 2.0 running the same repo validates and works properly.  Is this a bug in 2.3? or do I have to use a different type of repo?

When I try to reimport I get.

host-key add failed

Also I am using an external SFTP server

Can you create new repo to same server and see if it works. Use different repo name
