The bot used flask_sqlalchemy to error

[flllkis]

The bot using flask_sqlalchemy will report an error the next day

CR.CR_SERVER_LOST, "Lost connection to MySQL server during query"

pymysql.err.OperationalError: (2013, 'Lost connection to MySQL server during query')

You must restart the bot every day

Not a library issue.

不是图书馆问题。

Is it my code ？
I've already used the code
apihelper.SESSION_TIME_TO_LIVE = 5 * 60

The error itself is telling you the problem. MySQL server is failing at some point
