Error cuando se hace login

[eamanu]

Cuado se hace el login, (y me imagino cualquier otra interacción con la DB, se produce el siguiente error:

[2022-03-20 18:11:04,331][ERROR][app.gear.local.local_impl][(pymysql.err.OperationalError) (2006, "MySQL server has gone away (ConnectionResetError(104, 'Connection reset by peer'))")
[SQL: SELECT user.id AS user_id, user.username AS user_username, user.password AS user_password, user.id_person AS user_id_person, user.id_user_status AS user_id_user_status 
FROM user 
WHERE user.username = %(username_1)s 
 LIMIT %(param_1)s]
[parameters: {'username_1': 'admin', 'param_1': 1}]

[2022-03-20 18:11:04,331][INFO][app.auth.auth][getting user, attempt: 2]

lo que lleva a tener que reinterar varias veces (en este caso 3) para que se haga el login.
