Describe your problem

Title: MySQL connection issue after updating RAGFlow to nightly image (on friday 28.02.2025)

Description: After updating to the latest nightly image, RAGFlow is unable to connect to MySQL, and the MySQL container restarts unexpectedly.

1. Removed the existing container: docker rm ragflow-server
2. Started the service with the new nightly image: RAGFLOW_IMAGE=infiniflow/ragflow:nightly
3. RAGFlow started but constantly logged MySQL connection errors: peewee.OperationalError: (2003, "Can't connect to MySQL server on 'mysql' ([Errno 111] Connection refused)")
4. Rolled back to the last stable version, and RAGFlow started successfully.
5. However, when navigating to the Agents tab, the same MySQL connection error appears in loop and make a lot of errors.
6. Noticed that the MySQL docker container keeps restarting unexpectedly.

Observed Logs: Example from ragflow-server:
