Does OAuth2 have a limit number of connections? My app when many users connect, some login is in an infinite loop, then 70% can log in and 30% can not, is it something to do with connection limit?

ErrorException: explode() expects parameter 2 to be string, object given in /.../vendor/lucadegasperi/oauth2-server-laravel/src/OAuth2ServerServiceProvider.php:122

When you are passing callback function to the callback param in the oauth2 config you will get the error described. Probably this is why I'm using the very latest version of the lucadegasperi/oauth2-server-laravel...

if (array_key_exists('callback', $grantParams)) {
    list($className, $method) = array_pad(explode('@', $grantParams['callback']), 2, 'verify');
    $verifier = $app->make($className);
    $grant->setVerifyCredentialsCallback([$verifier, $method]);
}

You need to pass Controller@method callback there (or Controller@verify will be called if method is not defined). In the docs it's defined in a similar way https://github.com/lucadegasperi/oauth2-server-laravel/blob/master/docs/authorization-server/choosing-grant.md

Probably versions issue?
