“SQLSTATE [42S02]：在一次调用||后找不到基表或视图” Scotchbox || Laravel

I'm using Laravel 5.2 on a Scotchbox server.

Everything with the DB works as it should, but only for one call, or only a few seconds.

I can consult the "phpmyadmin" page, but also only once or twice. After a few second even this page gives me a 404 error.

I have to restart my scotchbox everytime to do something with the DB.

Laravel doesn't say it can't connect to the DB but says it can't find the table I defined in it:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'scotchbox.users' doesn't exist (SQL: select * from users where users.userId = 4 limit 1)

And when I want to connect to phpmyadmin again after it got stuck Laravel says:

NotFoundHttpException in RouteCollection.php line 161:

What did I do wrong?
