I had an HA running on proxmox installed using script by whiskerz007 and it was stable for some months, but recently it failed for some reason. I had a backup of the settings and set out to reinstall and reconfigure. Part of the reinstall was the Smartthings integration. I did not restore the settings, but rather have attempted to reconfigure mostly from scratch.
The following have been done:
Proxmox install script ran again (HassOS 3.5, 0.101.2)
Confirmed accessible via duckdns address
Attempted to add ST integration, but it failed
Ran hass_smartthings_remove which appeared to work successfully
Deleted /config/.storage/smartthings
Restarted VM
Smartapp was deleted successfully from Smartthings it would seem
Token was also removed from ST website
Created new token
Attempted to create new integration in HA with new token
“Unknown error occurred” displays
Log shows:

Am I just missing something obvious? Any wisdom would greatly be appreciated. It is simply amazing how quickly people can come to depend on the automation and voice control the system affords us. 
Thanks in advance for any help and certainly a HUGE thanks to all those that are much smarter than myself for all their work on this project!!
