I use pymysql to connect local mysql docker service like this:
conn = pymysql.connect(host='192.168.10.17',port=3306, user='root', password='test')

192.168.10.17 is my windows ip address, both dify and mysql-server are installed in docker desktop in windows.

docker config state : Docker subnet: 192.168.65.0/24 ; ✔ Enable host networking
dify config state : "squid.conf.template" is the initial state.
windows firewall state: added rules for 3306 allowed in/out

BUT there is a execution error :

File "/usr/local/lib/python3.10/site-packages/pymysql/connections.py", line 711, in connect raise exc pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on '192.168.10.17' ([Errno 101] Network is unreachable)") error: exit status 255

Is there someone help??
