Octoprint sever not active

Octoprint Server is not active after touch ui installation on 3.5 inch screen. Pi is plugged in and has power.(no undervolage)

Have tried updating and upgrading packages, have also tried to verify that the server is running via ps -ef | grep -i octoprint | grep -i python
doesnt work.

Help

Can you provide the octoprint.log so we can see if there are any errors from the last time it ran?
