Catalyst 9500 - SSH into another Catalyst 9500

[dal]

Do I have to configure something special to ssh from a Catalyst 9500 to another Catalyst 9500?

If I SSH into them from a Windows client, like a putty or SecureCRT, it works fine.

But not from one switch to another.

There are no ACL's involved, and the debug just says
SSH CLIENT: attempt to create connection failed
SSH CLIENT: failed to create connection

Any tips?

 There was a similar post here with no solution as fas as I know. On that case, it was happending between 9500 with different IOS versions. Is that your case also?

Yes, the firmware versions seems to be different, but it's still Catalyst 9000 switches, though

Another guys was facing the same issue. Tried to look into documentation but I did not find anything that could explain this behavior.  Maybe a new bug or some change on the IOS-XE prevent this access.
