I logged in for the first time in months. It suggested I update. I backed up and then tried the update. It got stuck with my trying to log back in. Now when I do the launcher there is no option to select my control console. The options are blank. What should I do to recover??

How long has it been updating?

First thing to try: are you able to ping your controller from a command prompt? If you can, then try manually adding the controller to the IoX launcher: click on "Add", and type in the URL. For example, if your controller's IP address is 192.168.0.123

https://192.168.0.123:8443/desc

Then try using the added line to connect to it.

If you can't ping your controller, you'll likely have to open a ticket.
