Unable to connect to ET server from MacOS client

[AHaymond]

Running MacOS 15.5 on an M4 MacBook Pro. Recently when I upgraded my server to 6.2.11 I suddenly could not connect to my et-server any longer.

I pulled down the et.rb file, changed up the version since it is behind (currently on 6.2.9) and used Homebrew to install 6.2.11 on my Mac just so both client and server were running on the same version.

The output from the connection attempt provides this:

The server is running and happy, and connected to 2022

However if I run the et-client in Docker on Mac. I can connect to my et-server running on Arch Linux. Which begs the question.... where is the bug??

The biggest changes in .11 are in the ssh config processing. Can you try moving your ssh config temporarily so we don't read it and instead feed the ssh settings directly?

If that isn't possible, can you confirm that it works with .9? We could diff the releases and see what's breaking you
