Zombie harvester (not started) keyError: 'port'

Hi, friends. I am sorry for the my noobquestion)
I am using:
Ubuntu 20.04.3 LTS
Python 3.8.10
Chia version: 1.2.11

Harvester does not run on this server. After looking at htop , I found him in a zombie . After removing the process and restarting it, I found errors in the port. I assumed the problem should be in config.yaml, although the data in it looks correct. Maybe it’s something else, tell me?

KeyError: 'port'

I didn’t find exactly the same problem on the forum, debug.log is empty, everything is fine on other remote harvesters and the local one

Apparently not configured venv?

All ok - thats something wrong in config.yaml
