You have a mysql permission problem, try this

mysql -uroot -pYourMYSQLpasswordOfChoice -Bse "GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.%.%.%' IDENTIFIED BY 'YourMYSQLpasswordOfChoice' WITH GRANT OPTION;"
mysql -uroot -pYourMYSQLpasswordOfChoice -Bse "GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'YourMYSQLpasswordOfChoice' WITH GRANT OPTION;"
mysql -uroot -pYourMYSQLpasswordOfChoice -Bse "GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.%.%' IDENTIFIED BY 'YourMYSQLpasswordOfChoice' WITH GRANT OPTION;"
ConnectionRefusedError: [Errno 111] Connection refused
pymysql.err.OperationalError while running site
ConnectionRefusedError: [Errno 111] Connection refused

@trentmu Thanks for the solution you suggested. In my case, the problem is a corrupt database :disappointed_relieved:.
