My opinion
-rw-r--r-- 1 root root 2251 Nov 25 07:55 mhn.log
It might not work correctly if it's not on the www-data user. Had that issue before. Same might be valid for mhn-uwsgi.log and mhn-uwsgi.err
Solution:

sudo chown www-data:www.data /var/log/mhn.log
sudo supervisorctl restart all

The all part isn't interely necessary but just in case.

Thank You for the information. It was a class project and the virtual machine has been eliminated (I had completed the course/class). However, I will keep in mind the suggested solution in case I encounter something like this in the future.
