Brand new eisy - update failure

Add me to the list of failed upgrades—I've had a 994 for about 10 years. I just got my EISY and it fired right up. I dutifully followed the instructions for migrating from the 994, which included a step to perform an upgrade. I saw a warning about waiting 30 minutes, but that it would continue to work. I clicked the upgrade button, and since then it has been unresponsive. I have since tried a factory reset (10 button presses), one button press for update, and five button presses for reboot. I have a 1G fiber internet connection, and my EISY is on the LAN, so it’s probably not a download speed issue. I also tried searching for the device using the mobile app, but had no luck. I can see both devices on my LAN. I tried https://192.168.0.193:8443/desc but received a refused to connect message. I guess I'll open a ticket as well—terrible new user experience. 

Update: I logged in with PuTTY - SSH - so eisy is still somewhat functional  -  Guess I'll try install command.

Update:  Using Putty - SSH  - I tried these commands found in this forum and was able to bring the eisy back on-line.  Now I'm having issues with the serial PLM not connecting.  
sudo pkg install -f isy
sudo pkg install -f udx

sudo tail -f /var/udx/logs/log ... wait till it either errors out (let me know the error) or successfully starts.

If successfully starts:   

sudo shutdown -r now

After eisy rebooted, it was instantly recognized by phone and IoX finder.

I decided to upgrade my eisy this morning (after successfully upgrading my test Polisy when 5.9.1 first came out in February). I ran into the same problem. ssh login worked, but no show in the IoX finder. Tried the power off/power on suggested by Michael above, but no go. So I went ahead with the pkg install instructions you posted, and it worked. Now fully operational again. I now have 5.9.1_13, which allowed me to configure a Matter bulb for the first time. The funny thing is that this morning it installed 5.9.1_12, and then redoing the pkg install after lunch upgraded to 5.9.1_13.
