SSH Corrupt Connection with aes256-ctr to Oracle Server

Hello!

We are on Zurich and support for the aes256-gcm@openssh.com cipher with SSH not being released until Brazil. We need a way to configure Oracle discovery and compliance. We worked with our security team and now have permission to us the aes256-ctr cipher, which is supported by Zurich based on the documentation.

With the aes256-ctr cipher, we are running into an issue getting the connection to work. When attempting to get SSH to connect we are receiving a corruption error (see attachment). When trying to run it from command line on the MID Server, we get a "Corrupted MAC on input" error. We're curious if anyone has seen this error before when connecting from a MID Server to an Oracle Server and if there is any guidance on how we can resolve this?

Thank you!
