IBC did not start my gateway automatically today, and it seems to be because of a popup asking to use SSL Authentication

--hung here without starting.
I manually ran the gateway using X and clicked the Accept button and it logged in. I then exited and IBC was able to start it as that popup didn't appear again.
I had the same issue with TWS 985, it also popped up the use SSL authentication when I logged in today. I had never seen that popup before.
