I am having the same issue. I reached out to Truenas Github team and was advised it was a DNS issue. I also reached out to the Linuxserver i.o. team on discord and was advised to reach out to the Kasm team. I have had no resolution to this issue and it seems I am not the only one. kasmtech/workspaces-issues#716

Check my issue again. I just updated it, it seems as tho setting the root dataset preset to apps was causing the issue for me. If I set it to generic or leave it to ix-volumes under the app install section it installs fine.
