Multiple login events from Broadcasting auth

Looking for some community wisdom... Recently we updated from Laravel 6.x to Laravel 9.x. Everything looks good, besides two strange things that I cannot find their source.

We are still using the laravel-echo-server and for now happy with it. However after upgrade we started to see two annoying things:

1. A lots of 403 errors now thrown during Broadcasting authorization checks. On Laravel 6.x we had none of them.

2. The multiple login events are dispatched when Broadcasting authorization URL accessed. Which we never faced before too. And the IP address in these events is an IP address of the echo server and not the user.

As for the additional information we don't work with tokens there, so it's a simple session authentication in Broadcasting and then some pretty simple checks on each channel level.

Thank you for any insights you may give!
