This morning I got an update for Core Shell and immediately updated it.
After completing the update (and updating core helper) I cannot connect to any of my EC2 instances, and I have many of those. I'm using ssh to connect to them. This is what I'm getting:
Connection failed, retry after 3s
[Abnormal Disconnect 16 Sep 2021 at 14:06:27]
I used iTerm2 and connected to instances without any problem. Prior to update, had no problems/issues with Core Shell.
