ssh key authentication fails if restarted in window with disconnected session

Asked by Simon Greenwood on 2019-03-13

I connect to a server daily for work using a 4068 bit key with a complex passphrase (this may or may not be relevant). I use Terminator with multiple windows and tmux on the remote machine, usually in a single window, and I usually have a couple of instances of Terminator running on my laptop. I move between wifi and a dock connected by ethernet during the day.

I had to rebuild my laptop a couple of months ago with Ubuntu 18.10 and since then I have lost persistence in the connection between wifi and the dock (which I think can be fixed) but if I try to log in again in the same window, my key is rejected. When this happens I can still log in in other terminal applications - tested with Gnome Terminal and Remmina, and if I kill the Terminator window and start it again, I can log in again. I can't see anything with ssh -v.
