Turns out I’m just an idiot. After trying a hail mary test of moving the keyboard nib into the back of the motherboard (again) the keyboard let me navigate through BIOS. Of course, all the USB settings were enabled lol and then I went to check the USB cable coming from the KVM, it had come partially unplugged.

Gotta love good ole user error!

Here’s the method I used from one of the issues on GitHub https://github.com/portainer/portainer/issues/12925#issuecomment-3516549977

Iirc my docker.socket wouldn’t let me just stop docker.service to edit it as described in the post, so I made /etc/systemd/system/docker.service.d/override.conf with the 2 required lines. After saving it and running daemon-reload I was able to access my containers in portainer again.

You can also add an override for the docker.service file to specify min api version 1.24. Had to do that last night
