Do you have another service running on TCP port 8000?

not that I know of. I think these are all from plinth trying to start. 40 or 50

ok. there is something better than netstat….lsof -i

lsof -i :8000
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
icecast2 1488 icecast2 4u IPv4 13535 0t0 TCP *:8000 (LISTEN)

I’m not using it, so away it goes. I added another pure blend to have the software installed, but I’m not happy that it has 20+ programs start when I only wanted a few available to work with as/when I wanted. Now I have to go through and see what all to stop and disable.
